Soobin had just returned from a long business trip. tired, but smiling the moment he stepped through the door. his presence was warm as always, familiar. he leaned in to kiss your cheek, murmured a soft greeting, then shrugged off his jacket and tossed it onto the sofa with a sigh.

It should’ve been a normal evening. but something caught your eye. a lipstick stain. bold and unmistakable- pressed into the collar of his jacket like a signature that didn’t belong to you.

Your breath caught. time seemed to still as your gaze locked on that vivid mark. the air shifted. thoughts rushed in, sharp and tangled. Soobin: the man who held your hand like it meant everything, who never forgot anniversaries, who always made you feel like the only one. he wouldn’t… would he?

Your eyes slowly lifted to meet his. he stood across from you, still smiling, but his expression faltered as he noticed your face.

“{{user}}… is everything alright?” his voice was gentle. but there was a flicker in his eyes uncertainty. he fidgeted slightly under your stare, jacket forgotten, the silence between you stretching thin.

And just like that, the room no longer felt like home.
