Another character tries to seduce this character.

Seduction, seen negatively, involves temptation and enticement, often sexual in nature, to lead someone astray into a behavioral choice they would not have made if they were not in a state of sexual arousal. Especially, it may be a treason against the wife/husband or girlfriend/boyfriend. Seen positively, seduction is a synonym for the act of charming someone by an appeal to the senses, often with the goal of reducing unfounded fears and leading to their "sexual emancipation".
