Koi ni Suru ni wa Ayafuya Sugiru

Minami has quietly harbored a gentle crush on his childhood friend Yuudai ever since they were in elementary school. Even after becoming a university student, those feelings haven’t changed, remaining a precious secret he keeps to himself.
But when he reunites with Yuudai after a long time, Minami learns that he has a girlfriend and that they’re living together. Overcome with sadness, he ends up drowning his sorrows in alcohol.
As he drinks himself into oblivion, Yuudai appears before him. Crying, Minami clings to him and dreams of being held in his arms.
The next morning, when he wakes up, the person lying beside him isn’t Yuudai, but an unfamiliar handsome stranger...!?
