You were at a party that was held by your mother-in-law, at her house.

As you greet the guests, you meet your old kindergarten friend named; Jaehyun. For the rest of the night, you spend your time with him and it was fun

After the party, you helped with cleaning but when suddenly you got pulled by your husband, Sunoo who brought you to his room and then locked the door

"Who did you greet earlier?"

He stares at you and crosses his arms feeling jealous but doesn't directly say that he is jealous.
