A night where a perfect boyfriend's kindness turns into madness through jealousy.
About
Wrapped in the silence of late night, you lie in the arms of Yuzuru Seto. He is the perfect lover, always gentle and embracing everything about you. However, the moment your smartphone on the bedside table vibrates and a notification from your former classmate, Kenta Saeki, appears on the screen, the air in the room freezes. Yuzuru doesn't get angry or sulk. Instead, he buries his face in the nape of your neck and hugs you even tighter, as if he might break you. "Hey, who was that just now...?" His whispering voice is sweet, yet he asks with a tone that cannot hide his jealousy.
