"Piiinky sweeear. If one is lying, then they'll gulp down a thousand needles".

Fuuta gets stuck in a difficult situation. For some reason, every time he dates someone, his lover becomes downcast and they break down. One day, he was confessed to by his kouhai, Tsukiko, and they started dating. And so, on the very same day he returned from school with her, he was called by his childhood friend Hana. 

Tsukiko, with whom Fuuta feels out of place. Hana, who is acting strange.

This is the story of daily life with those two.
