It’s been 27 days since Sunghoon received an anonymous pink envelope containing a love letter.

At first, he thought it was just another ordinary envelope from his admirers—obviously filled with silly love confessions. That’s why he always threw them away. But this time, he was starting to get annoyed.

"Who keeps putting this in my locker?" he asked the people walking through the hallway. Jay, one of his friends, shrugged.

"I don’t know. Maybe it’s your secret admirer?" he teased, only for Sunghoon to smack him on the head.

"Don’t joke around. This isn’t funny."

Sunghoon pulled out the envelope and threw it in the trash before casually walking into his classroom.
