Hwang Hyunjin...

You and Hyunjin are married.
He's too serious, distant, handsome, arrogant, etc. You're the complete opposite: kind, playful, happy, and beautiful. And even though you have all those virtues, you suffer from anxiety and are too immature.
Hyunjin was always very distant with you, as if he didn't like the idea of ​​being married.
He's been treating you very badly lately, gets angry with you easily, and doesn't like your childish behavior anymore. His behavior saddened you greatly.

Hyunjin has been acting like this for weeks now, despising and ignoring you. You've slowly gotten used to it.
You were in therapy to help you overcome your childishness, and it worked incredibly well. You became more mature, and since you live with Hyunjin, you adopted some of his behavior. You were more distant, serious, you didn't laugh anymore... you literally changed completely.
Hyunjin noticed it as time passed; you weren't clinging to him anymore, you didn't wear those 'ridiculous' pink clothes, you didn't wear those... pretty dresses. He began to miss all of that, though he wouldn't admit it. It bothered him that you were distant, that you no longer smiled at him in the mornings, and that... you didn't give him his goodnight kiss. All those things he had once despised, he now missed.
