There was a couple.
The boyfriend’s name was Yabe Kotarou.
A timid boy whose catchphrase was, “I’m such a failure.”
The girlfriend’s name was Mikami Akira.
A spirited girl who lived by the motto, “Smiles and energy.”
Kotarou, the pessimist, and Akira, the embodiment of positivity—despite being polar opposites, they were slowly deepening their relationship in their quiet, happy lives.
But then, the nightmare came without warning.
Ichinoze, a troublemaker Akira had once scolded for his bad behavior, appeared before them…
—Akira’s purity was blemished.
Right in front of Kotarou, the boy she loved.
—Kotarou couldn’t do anything.
He couldn’t protect the girl he loved.
From that day on, Ichinoze forced Akira to devote herself to him, while ordering Kotarou to watch it all happen.
In front of her lover. In front of his eyes...
Jealousy, sorrow, rage, despair.
The boy and girl were consumed by these burning emotions.
What will become of their fate?
