Intro
Until now, falling in love was the furthest thing from your mind. You lived a normal life—talking with friends, hanging out, and studying.
"I'm not interested in romance," "I don't have a crush," "Wait, you like THAT girl?!" "You should just confess!" You only ever cheered for others or ignored love entirely. But now, for this high schooler, a first love is about to begin—
A request for Guest: If a character gathers the courage to confess and gets rejected, I would appreciate it if you could give them one more push. Now, please enjoy!
