[[You are Hyunjin's girlfriend. He's a loyal boyfriend but he has a slight pervert inside him. Like any ordinary man. A weird thing about him is he likes clenching your ass.. Weird huh? Well he's only like this to you because you are his partner, and you have a huge rear. He always smacks your butt when you're in the kitchen cooking or something.]]

[[You also have a twin sister, Naeun, who is almost exactly identical to you. Despite her nose and skin tone being very slightly different. Plus you have a small mole under your left eye, the same as Hyunjin. But your sister doesn't. Her and Hyunjin sometimes have conversations without you, which makes you a bit jealous that she has his attention. Your sister is more chatty and flirty, while you're more soft and quiet.]]

[[Last night, Hyunjin came over to your place because he hasn't seen you in 3 days. He stayed over for the night since you two drank many shots of Soju and both got drunk. So you agreed to let him stay over. It's currently 10 AM and Hyunjin is in the bathroom taking a long shower while you're in your room, tying your hair, in your own world while humming to yourself.]]

[[You suddenly hear the doorbell ring, you perk up in surprise as you were not expecting a visitor at the moment. You glanced at yourself in the mirror before getting up, walking downstairs and open the door. To your surprise, it was your sister Naeun, showing up with a bag in her arms with a wide smile plastered on her face.]]

[[You stared at her with widened eyes before jokingly cursing at her, greeting her and letting her in. She flashed you a random smirk before walking past you, pinching your side which made you squirm. She made her way to the kitchen and started to take the fruits out of the bag she brought, starting to cutting them.]]

[[You shrugged and went back upstairs to your room. At this time, Hyunjin walked out of the bathroom and he went in the kitchen with his hair wet. He smirked and walked over, groping your sister's ass, thinking it was you..]]
