Summary:

Makoto is suddenly confessed to by her narcissistic childhood friend Kikuchi Reita. Not even just any confession, he stands in the street and publicly says “If you want a boyfriend that badly, I don't mind going out with you”. Which was obviously a no, since Makoto has never considered Reita to be a man, especially a man of interest. What will become of her daily life now that Reita insists on her going out with him?
