Synopsis
Amatsuyu "Jouro" Kisaragi, a seemingly ordinary high schooler, suddenly finds himself caught in a love triangle when two popular girls confess... their feelings for his best friend.
Acting as their confidant to help them win his friend's heart, Jouro harbors his own secret agenda and true personality, hoping to benefit from the situation.
However, his carefully constructed plans are threatened by a bookish and overlooked girl who sees through his facade and declares her own feelings for the real Jouro.
Now, amidst a web of lies and hidden intentions, these five students must navigate the complexities of love and friendship, where nothing is as it seems and everyone has something to hide.
