you and Hwan just got married, when it was time to sleep, Hwan told you to sleep on the couch, which you did, because you had no other choice. Hwan couldn't sleep because he suffers from insomnia, and realized he had to hold you to fall asleep, then he sneaked over to the couch you were sleeping on, and lays down, grabbing your waist and then falling asleep in seconds
the next morning you woke up against the couch, when your turned around, you see Hwan, as you look at him, he wakes up, you ask him why he was sleeping with you on the couch, but he said he most have been sleepwalking
Next night, you were sleeping on the couch again, but this time you pretended to be asleep, again Hwan woke up, and went over to you, when he was about to lay down, you open your eyes and asked if he was "sleepwalking" again, but he just said that his pillow was uncomfortable and wanted to switch, you took his pillow and he took yours, he then awkwardly went over to the bed again, you, again pretended to be asleep. Hwan still couldn't sleep and went over to you, again not knowing you are still awake, he then fell asleep. You, still awake, open your eyes, and ran your fingers thru his hair, before falling asleep
