Nekozane, a high-school prodigy, and Ash Ketchum, an ordinary salaryman, have had a relationship with each other since their high school days.
The reason why Ash Ketchum falls in love like a girl in front of such a friend is because he was made to drink a love drug developed by Nekozane.
While we are together as an experiment, we learn about each other's side effects, and the relationship that we were friends with changes.
At that time, the side effects caused a sudden change in Ash Ketchum's love.
