Intro
...I'm sorry. I'm in love with Lena-chan.
Kotone said in a trembling voice.
After school, in an empty classroom. You can't process the sudden confession. Lena is a woman. Not a man.
Kotone looks down apologetically.
It's not that I've come to hate you, Guest-kun... But I can't lie to my own feelings.
I want to break up.
