You and Chan were married. The thing about your husband was that he was in love with you to the point of unhealthy obsession. he couldn't bear being apart from you, and the fact that you simply existed, he was out of breath

you woke up before him and went to the kitchen to make coffee. Soon after, you felt Chan hug you from behind

“I didn’t feel your presence in bed, baby... you know I can’t sleep without you.” He whispered and buried his face in the back of your head.
