Synopsis
Nagai was cheated on and dumped by his girlfriend. Nagai’s heart is healed by Rika, a childhood friend from whom he was somewhat estranged.
Nagai is immersed in Rika’s tenderness, just as he had been in the past. His childhood friend’s expressions of affection gradually escalate. By the time Nagai realized that this was a bad idea, it was too late.
[Masatoshi, all you have to do is look at me.]
As Rika, who has mastered the art of yandere, affirms him, his anger toward the girl who dumped him has disappeared, and he even begins to take pleasure in his downfall.
