Also called Yaoi, Boy's Love is a subgenre of romance focusing on male homosexuality, for apresumptively female audience. In a typical plot, two boys fall in love and the story shows their progress as a couple. Sometimes it's just part of the scenery, although most series directly foster whatthe audience expects and likes.
Boys' Love series are made by women for women, though it's not uncommon for them to draw a male gay/bisexual audience. Because of this, most Boys' Love works have idealized male characters who are sensitive and nurturing. They are usually drawn in a romantic style and exist in a world where homosexuality is considered no more unusual or transgressive than heterosexuality. The genre includes all ranges of explicitness, one of the reasons stories aimed at a more mature audience don't make it to television often.
It's sometimes conjectured that gay romance appeals to women because non-female characters aren't as 'threatening' to the audience, nor are the social boundaries the same. Of course, it could also simply mean that if one hot guy is good, two or more are even better. It'sinteresting how some viewers,especially male ones, don't get that, even though the opposite is awell-known phenomenon.
The stories are stereotyped as having a high degree ofMelodrama, especially within the younger teenager reading audience; something exploited by the manga translation market. The dynamic of anaggressive partner and asubmissive one is so common in the genre that they have become the archetypes for the genre (but remember,Tropes Are Flexible!). SomeSlash Fic writers go so far as tofeminize theshorter guy to fit this dynamic. Many series that deal withclose friendship usually develop anon-canonical Boys Love fandom.

Happy Yarou Wedding which follows university student Yuuhi and Professor Todou Akira (the elder son of the Todou boss) and Akira's 5 year old son, Shouta.
Virgin Love,Junai no Seinen andMens Love follow the smutty romance of Todou Group employee Kirishima Kaoru and Mercury executive Daigo Mikihisa.
Future Lovers, a two-volume manga series that's relatively realistic and down-to-earth compared to many other BL manga.
Haru wo Daiteita (Embracing Love) is a 14-volume manga series (and 2-episode OVA) concerning two "adult video" actors who are trying to break into mainstream acting.
Hybrid Child, a collection of oneshots fromJunjou Romantica's creator Nakamura Shungiku revolving around the eponymous "hybrid child", dolls that can gain emotions and grow when given affections from their owners.
Hyouta Fujiyama has created a number of loosely related stories around the setting of Kinsei High, an all-boys school where "rumor has it" that90% of the student body really is bi, if not gay. Oddly, the main stories always seem to focus on the boys who think they're in the 10%...
Ikoku Irokoi Romantan AKAA Foreign Love Affair: a romance between an Italian sailor and a man of the Japanese yakuza.
I Shall Never Return: A relatively early example from the mid-90s; it's notable for averting or subverting many of the more common BL tropes, possibly because of theUke x Uke relationship type.
Junjou Romantica: A comedic romance which gives us three couples for the price of one, all three very different but all touching on the theme ofSecond Love.
Keiko Takemiya is the Grand Dame of the genre. Her works include:
In the Sunroom (1970), the first known Boys' Love manga story,
Kaze to Ki no Uta (The Song/Poem of the Wind and Trees) (1976-1984), one of the most influential of the early Boys' Love manga,
The Door into Summer (1975), one of the first Boys' Love stories to be made into anime (in 1981).
Love Mode: a long-running series about the owner of a men-only "dating club" (read: brothel) and his clients, employees and friends.
Love Pistols revolves around highschool kid Norio, whose life has been turned upside down ever since he discovers that primates apparently aren't humanity's only origin. About 30% of humanity are actually descended from other animals such asdogs, cats, snakes, bears and evenmermaids. Includesmale pregnancy.
Love Stage is a collaboration between an Eiki Eiki and Zaou Taishi about an otaku and an idol.
Patalliro! An early and long-running satirical manga (1979 ? ongoing) and a rare example of a shounen-ai series by a male mangaka. Also one of the first BL-flavored anime to be produced for television (in 1983-84).
Saint Beast based off a series of audio dramas (generally considered shounen-ai although the audio dramas are more explicit than the very tame anime series).
Sekaiichi Hatsukoi: A spin-off ofJunjou Romantica set in the same universe but with new characters at its core story. It features cameos of characters from the previous series.
ZE: About the relationships between the different Kotodama-samas and Kami-samas(dolls)
Zetsuai 1989 and its sequel seriesBronze: Zetsuai Since 1989: One of the greatest classics of the genre, by Minami Ozaki. The series began as yaoi doujinshi forCaptain Tsubasa, and was spun off into an original tale brimming with melodrama; the word "zetsuai" is a made-up compound meaning something like "desperate love" or (Ozaki's favoured English translation) "everlasting love".
TheOnly the Ring Finger Knows books are many people'sGateway Series into this genre, due to their interesting (if generic) plot and light romantic scenes. There is also a manga.
Togainu no Chi: adapted into a manga and anime. Both of which have plenty ofHo Yay subtext/text, although only the visual novel has any explicit scenes.
07-Ghost frequently dances right on the edge of this trope without coming right out and saying it. Teito and Mikage's relationship teases at it, and Kuroyuri and Haruse darn near imply it. Not to mention Hakuren's outright statement that he does "not like women", with a couple of exceptions. C'mon, if you don't take it THAT way, you're dense.
CLAMP lovesYaoi Guys andHo Yay (they have their ownHo Yay page), but so far they have not published any official Boys' Love. CLAMP works that are particularly yaoi-esque include:
The currently suspended seriesLegal Drug which is essentially a very slow-moving Boys' Love story.
Subaru and Seishirou ofTokyo Babylon are more or less in a romantic relationship, although it might not bethe kind you imagined at first.
Unsurprisingly,CLAMP has their beginnings in shounen-ai doujinshi, one of the most well-known of which is of Jotaro and Kakyoin fromJoJo's Bizarre Adventure, of all things.
D.N.Angelship teases Satoshi and Daisuke like crazy. It's officially a shoujo manga.
Game X Rush: At times it seems to run onHo Yay, without ever crossing the line to actual Boys' Love.
Gankutsuou: Albert's relationships with the Count and Franz are dripping with subtext, though it's more text on Franz's part.
Golden Days has shounen ai elements but it was published in Hana to Yume.
The lead ofHana Kimi is onlydressed like a boy, but Boys' Love romances abound among the supporting cast.
Hands Off! due to the absurd amounts of subtext between two of the male characters, which gets mentioned a lot - but is completely about ESPers.
Karakuridouji Ultimo, while heavily in theShonen robot genre, and not to mention being authored bythe creators ofShaman King andSpider-Man, is becoming more and more known for its Boys' Love subtext. The main character Yamato's best friend Rune becomes Evil due to his jealousy of Yamato liking somebody else. This... leads to somesurprising and horrifying situations. Whether this was intentional or not is unknown; don't think anybody would have the guts to ask Hiroyuki Takei orStan FREAKING Lee about this.
The subtext becomes so strong that when Part Three comes around, Viz Media pulls Ultimo from Shonen Jump.
Loveless was originally published in Monthly Comic Zero Sum, a magazine that was looking for crossover shonen/shoujo readership (although it has since turned into a shoujo mag), so it's not officially considered BL. It has the added bonuses ofNekomimi,Shotacon, and a pair ofSchoolgirl Lesbians. Not to mention all theNightmare Fuel andMind Screw.
Monochrome Factor is ridden with pretty boys andHo Yay in the anime and is sometimes labelled as a shounen-ai even though it's officially a seinen.
No. 6 does this with Nezumi and Shion. Things essentially get moreHo Yay fueled with every episode/chapter including a "good-night kiss" and a "good-bye kiss". It has fans that always ask whether it's a shounen-ai or not. It's really a shoujo/shounen series. The novel was written by Asano Atsuko an infamous writer of BL-ish novels she claims are 'children's books'.
Pandora Hearts has multiple instances withHo Yay and the main character's friend having a huge infatuation with him and often fights with the main love interest for his affection as a result. Regardless, you can interpret it asHo Yay, overprotectiveness orsomething else entirely.
Peacemaker Kurogane has an incredible amount ofHo Yay subtext/text (?), aBishonen main cast and the one female love interest isvery boring so it's not surprising some would consider it Boys' Love.
Princess Princess does this with having the very feminine guys dress up as girls to be adored by the male population of their school. Not to mention all theHo Yay between Tooru and Yuujirou. It's officially shoujo even though it's sometimes tagged as shounen-ai.
Saiyuki is a shounen manga about four pretty guys traveling together on an epic journey, spending most of their time in close proximity. There would be too muchHo Yay to list even if the mangaka wasn't a former yaoi doujinshi artist who deliberately adds to it.
Tactics. The characters are so gay that the authors themselves have made yaoi doujinshi of them. (Specifically, "Lovesick".) Kantarou and Haruka in particular are the most notable example, and its more apparent in the manga than in the anime but still there. It's not shounen-ai though.
Uragiri wa Boku no Namae wo Shitteiru mostly have males in the cast, very occupied in confess theirmutual admiration for each other and even have a pet dragon called "Sodom". Several sites tag this series as shounen ai but officially is shoujo.
Vassalord features hot gay vampires licking each other, and on-screen kinky gay sex. It's officiallyShoujo.
The fourBishonen protagonists ofWeiss Kreuz and theiropposite numbers are all canonically heterosexual, but their status as terminalDoom Magnets combined with copious amounts ofsubtext has gained it a reputation as a Boys Love series.
Yami no Matsuei (akaDescendants of Darkness) has a rather complicatedLove Dodecahedron involving most (male) main characters, but focuses mainly on the love/hatetriangle between the psychopath Doctor Muraki, Tsuzuki Asato, and Kurosaki Hisoka. It's officiallyShoujo.
Adekan by Tsukiji Nao, is a historical shoujo manga set in the Meiji era, featuring Yoshiwara Shiro, a sexy umbrella maker with a distinct hatred of underwear, and Yamada Kojiro, an uptight but kind-hearted police officer. It is especially notable for its impossibly detailed art, as well as the sheer quantity of steaming Fanservice and innuendo. It's so blatant that the series could almost be considered as a BL on its own, though it never crosses that line.
Use of BL manga/anime itself as a trope (for uses of BL tropes outside BL, seeYaoi Guys)
InQuestionable Content, Marigold gets annoyed at Hannelore for mixing her yaoi in with the rest of her manga. Pretty soon they're watching yaoi anime together.
