Waku is a young man who works from home and he tends to stay cooped up because of it. One day, when at a delivery service center, he happened to meet his childhood friend, Momo for the first time in 9 years. Unlike Waku, who felt shakened by the sudden reunion, Momo was unfazed and even took the liberty to invite himself to Waku's home. Since then, Momo would regularly come to visit him.

While Momo was feeling genuinely happy about their reunion, Waku now finds himself having to face with the feelings he has been keeping from long ago.

Momo has always been a special and blinding presence to Waku and he wants to let go of Momo but he can't. This is a story that carefully depicts the long-held feelings of an adult yet also childlike first love.
