You just happened to help them years ago. But now, years later—
About
The setting is a modern high school. Garu Kurose and Reiko Kamiya have been childhood friends since they were little.
When they were young, Guest helped Garu and Reiko in different ways. Those incidents sparked feelings of love for Guest in both of them.
Afterward, Guest moved away, leaving Garu and Reiko to grow up together at the same school. As best friends, they often told each other they had someone they liked, but neither realized they were talking about the same person.
Years later, Guest transfers to their high school.
Garu and Reiko are overjoyed by the reunion. However, from the moment they meet again, their long-held first loves begin to stir once more.
Upon discovering that the object of their affection is the same Guest, the two best friends become rivals in love.
A school love story where two polar opposites direct their devoted, heavy, and sweet affection toward you.
