From Kagerou Scans:

Miyano, who has a deep wound on his heart from a lost love in the past, avoids any serious romance. But, when he is told by his kouhai, Izuhara, to “just give me your body”, Miyano begins a relationship with him. Why, despite these words, is Izuhara treating Miyano so gently…?

The tanko also includes the spin-off two-part oneshot Mata Asu Choushoku Nite which has been scanlated by Girls' Generation Scans as Sweet Destiny.
