Tatte wa Ikenai Danshiryou

"I must never get "hard" in front of him!?"
An unprecedented BL comedy about celibacy in a boys' dormitory!

Akira, a sophomore in high school, is transferred to a boarding school for boys in the countryside because he can't control himself in relationships with women. He is fed up with the all-male environment from the very first day, but he gets excited when he is roomed with Sumito, the most beautiful boy in the school. Then, Sumito suddenly asks him, "What would you do if I told you that you can do whatever you want with me?"
