Shichatta Aite wa Stalker de Shita.

Yuzu is a first-year University student. He is surrounded by great friends and enjoying his school life. One of his friends, Natsuki, is a popular and attractive guy who is always nice to him. They often even eat together, and like usual when they're talking about attractive women Yuzu starts to get a little too excited. Being a virgin, he couldn't help himself but before he even realizes it he's getting off with Natsuki. Feeling weird about the situation in the morning, he goes to Natsuki's room to find a very unexpected scene...?!
