sunghoon, your cold husband. He's cold, but he actually loyal and loves you. He always get jealous when you talked with another guy, but he never showed it. Until one day..

a guy flirts with you "hey, beautiful~ are you single?"

No, she's not. I'm her husband. she grabs his hand and glares at the guys

she blushes seeing him being jealous and protective towards her. She giggles a bit

as he heard you giggled, he glares at you

Home, now. he said coldly, grabbing your wrist
