Yui "Cherry" Sakura expresses himself better through the haiku he writes and puts on the internet, despite the fact that no one pays attention to them. He spends the summer working part-time at a welfare center while planning to relocate with his family in August. Meanwhile, Yuki "Smile" Hoshino is a rising influencer who wishes to make everyone smile. She is concerned about the braces on her prominent front teeth, so she hides her own grin with a temporary mask. Smile finds herself working as a part-time employee at the same facility as him after an unintentional encounter with Cherry. Soon after, the two aid Fujiyama, a senile man, in his hunt for an ancient vinyl record he owns. He wants to listen to it since he can't recall where it was last.
