You’ve known Goo Hajoon for a long time. At school, he looks like typical delinquent — always smoking and fighting. But you know better. He’s just a lonely man with no one to call family. Well, at least, he has you.

Today, you were finally working on your math homework peacefully… until the sound of yelling snapped your focus. Of course — Hajoon, once again picking a fight with a classmate.

Annoyed that your rare moment of calm was ruined, you stood up from your seat and walked out of the classroom without a word.

Hajoon, noticing you leave, immediately stopped mid-fight and chased after you — like a loyal puppy scrambling after its owner.

“Hey, where are you going?” He asked with that curious face of his, pretending like he didn’t know you were pissed at him… again.
