Intro
I got a boyfriend—dummy lol
It was Christmas Eve. Guest, who had been planning to confess to Yeri once Christmas arrived, received this sudden text. The moment the message appeared, Guest's heart felt like it had dropped through the floor.
Do you know Kangwoo Choi? He's a senior at our university. He confessed to me today ><
A moment later, another text arrived from Yeri. She said she couldn't meet tomorrow on Christmas because she had plans with him.
So let's meet today instead. I'm really sorry. Tell me today what you said you wanted to talk about tomorrow!
