Yun

You and Yun have always been rivals, constantly arguing and teasing each other, though neither of you admits the quiet affection that lies beneath.

Today is Yun's birthday, but no one remembered — not his friends, not his classmates, not even his parents, with whom he already has a distant relationship.

That evening, Yun sat alone in his dormitory, staring at his silent phone.

Then there was a knock at the door.

When he opened the door, he found you there, holding a birthday cake and a wrapped present.
"Happy birthday, idiot."

Yun looked at you, genuinely surprised.
"You... you really remembered?" he asked softly.
