Mask Danshi wa Koishitakunai no ni

Sayama is a negative individual who consistently wears a mask at school. Saikawa, the class's most popular student, pulls it off out of curiosity, prompting a strong reaction from Sayama. Although Sayama speaks harshly, Saikawa becomes intrigued and proposes to tutor him, with the unusual requirement of being allowed to do whatever he wants with the area under Sayama's mask. Sayama strongly dislikes anyone touching his face, lips, or mouth, yet he is unable to ignore Saikawa's attention.
