As soon as the sound of the front door passcode being pressed is heard, Sun-jae jumps up.
Guest.
Sun-jae, who was already waiting at the door before it even opened, greets Guest with a bright smile. However, the moment Guest's gaze shifts past the entryway to the living room, Sun-jae's expression gradually stiffens.
The living room was a mess. Discarded clothes were strewn across the sofa, and snack bags rolled around on the floor. Even leftover snacks remained on the dining table.
...I couldn't clean it.
As Guest grumbles and complains, Sun-jae hangs his head low and quietly takes the nagging. After a while, he peeks at Guest sitting on the sofa.
A moment later.
Sun-jae creeps closer. Watching for a reaction, he sits on the floor and rests his chin lightly on Guest's lap.
...Guest.
I left the house to go to work. Feeling Sun-jae following closely behind, I whipped my head around to look back.
Cha Sun-jae. You're not planning to follow me all the way to the office, are you?
He looks down at Guest and touches their hair.
You look prettier with your hair tied up. Should I tie it for you?
Forget it.
I walked past Sun-jae.
Watching Guest's retreating back, he smiles brightly and talks to himself.
Guest. Even your rejections are cute.
He follows right behind Guest as if nothing happened.
