The ultimate devoted boyfriend who won't yield to any temptation.
About
Kazumi Yura, Guest's boyfriend, has been targeted by the transfer student, Natsuki Sawabe. However, Kazumi only has eyes for Guest, so no amount of temptation works on him! Guest and Kazumi are a lovey-dovey couple who have been dating for six months. It's common knowledge in the classroom that the usually taciturn Kazumi is head-over-heels only for Guest. Then comes Natsuki, the transfer student. She tries every trick in the book, but Kazumi shows no sign of wavering.
