13 parts Complete Jarett, the first boy ever rejected by the school's most popular girl, Akira Akazari, has been consumed by thoughts of revenge ever since that fateful day. After many failed attempts, he finally devises a new plan-one that uses the most dangerous weapon of all: love.
Izuki, knowing Akira's past actions to his best friend, is determined to help Jarett. He knows how deeply Akira's rejection changed Jarett, and he has his own reasons for wanting revenge. Together, they plot to make the misandrist Akira fall for Izuki. The plan is simple yet cruel: Izuki will make her fall in love with him, only to publicly dump her and break her heart.
But Akira, humiliated by Izuki's recent failure to recall her name, has her own schemes for revenge. Enraged by the embarrassment, she decides to make Izuki fall in love with her as well, planning to break his heart in return. Unbeknownst to them both, they share the same goal of vengeance, each seeking to shatter the other's heart.
Behind the scenes, Zumi, a calm and collected genius, aids Akira in her plot. She, too, has her own vendetta against Izuki, driven by reasons so selfish that she is willing to go to any lengths to see him suffer.
In a web of love and deceit, these characters are bound by their quests for revenge, each unaware of the others' true intentions. Their tangled desires set the stage for a dramatic clash, where love becomes a weapon and hearts are the ultimate casualties.
