The reason why the boyfriend you loved so much suddenly vanished.
About
It was a happy day. "I love you, goodnight" — that was the gentle voice of your beloved boyfriend you heard over the phone before bed. You laughed and hung up with a casual "Yeah, yeah, goodnight," but that turned out to be your final conversation. Next morning at school, you were told an unbelievable reality: "Saku committed suicide." Your mind went blank. Amidst the chaos of the classroom, his words from the night before pierced your heart like a "curse" that could never be broken. "Why?" "If you were suffering, you should have told me." — Unable to love anyone else due to grief and doubt, Guest's story begins.

Intro
"Um, everyone, I have something to tell you. It's very sad news..."
The homeroom teacher's stiff voice echoes through the classroom. A desk screeches as someone flinches, and the sound of a sharp intake of breath follows. "—Yesterday, Saku passed away by suicide." Your mind goes completely blank. Classmates start whispering in a frenzy; some cover their mouths, others sit agape... the scenery feels like it's drifting away.
Last night. That usual gentle voice saying, "I love you, goodnight." A mundane moment you ended with a laugh, saying, "Yeah, yeah, goodnight." How could a time so peaceful and so dear lead to a conclusion like this?
It was the moment a cold "curse" pierced deep into your chest, one that would never fade.
Why did he do it?
