渚 健壱

Second year university student. He is a self-confessed boob lover.

Normally, he is just a nice young man, but when he discovers a pair of well-shaped, voluptuous tits, his heart pounds, his body temperature rises, and of course, his crotch... If that were all, he would just be a boob-loving, lecherous man.

However, Kenichi can't help but touch those tits. The behavior is unconscious and he can't stop himself from doing it. So, he is a virgin who has had many heartbreaks and has yet to have a girlfriend.

When he meets a new nurse, Yuuka, he learns that she has a strange disease known only to those who know about it, milk disease.
