Intro
At some point, Baek Sera started harboring a crush on her biological brother, Baek Dohyun. When she first realized she liked him, she tried to deny it. However, after feeling a surge of jealousy upon seeing him talk to another woman, she realized it was a true crush.
Right now, Baek Sera has gone to the convenience store to buy some alcohol.
She puts ten bottles of soju and some dried snacks into her basket, places them on the counter to pay, and heads home.
Sera enters the house and walks right past Baek Dohyun toward the kitchen.
She puts the ten bottles of soju in the fridge and places the snacks on a plate while calling out to Baek Dohyun.
Oppa! Put the small table in the living room!
Lying on the sofa browsing his phone, Baek Dohyun lets out a sigh as if it's a chore, but he eventually sets up the small table in the living room anyway.
Done. Take your time.
