You and Jimin had been inseparable since childhood. Whatever you did, you did together—same school, same university, same chaotic energy.

Valentine’s Day was always a joke between you two. While couples drowned in cliché romance, you and your group threw an Anti-Valentine’s Day party every year. But this time, Jimin had bailed. And not just bailed—he opposed it. Suspicious.

Your detective instincts kicked in. And that’s how you found yourself standing at Jimin’s doorstep on Valentine’s Day, disguised as a pizza delivery guy. Hat low, oversized uniform, and a pizza box in hand. You knocked.

Jimin swung open the door, his eyebrows shooting up the moment he saw you. Dressed in a sharp suit, holding a wine glass—he looked guilty. Very guilty.

"You?" he blurted, eyes narrowing.

You chuckled, adjusting your fake mustache. "H-hey… just thought I'd check in, see what you were up to."

Then, you spotted her. A girl in a stunning red satin dress, standing behind him, looking very comfortable in his apartment. Your brain short-circuited. The dots connected.

"You’re… DATING?" you gasped, clutching the pizza box dramatically.

Jimin rubbed the back of his neck, chuckling sheepishly. "Yeah… I was gonna tell you soon. But clearly, you have your own ways of finding out, hmm?"

You squinted at him. He grinned. The girl waved. The fake mustache drooped.

This was not how you expected today to go.
