Touch Me and Melt Me(2007)

Sawatte, Tokashite.

Tatsuya is a second year high school student whose tutor, and subsequently his father’s subordinant, tells him "I’m in love with you," and suddenly kisses him! Since then, even as he repels Saejima, Tatsuya is hyper-aware of him, but Saejima is constantly joking around, and Tatsuya doesn’t know how far he’s being serious.

Why is it that the mature looks on Saejima’s face make Tatsuya’s heart to throb, and feel every touch?! A cute, slightly sinful, collection of stories.
