One Helping of Sweet Love
Senga is an unmarried office worker whose one high point of the week is going to her favorite bar and seeing the handsome bartender, Kayaba, who always treats her kindly. After she drunkenly comes onto him one night and he seems open to the idea, she asks him about a relationship, but he worries that his ED will get in the way. She assures him it won't and they start dating, with Kayaba enjoying pleasuring Senga even if he can't get it up, but when she tries to do something for him and gives him a massage, he gets his first erection in three years. It's good news, except that now Senga is wondering what trauma happened three years ago to cause this. Excellent male lead, very good at consent, and the female lead is strong and likable as well. No trigger warnings.
