You're Hae Run's brother, and you're dating... He Run is three years older than you, he's 20, and you're 17. Your parents don't know you're dating, they think you're just very good brothers. Your parents are on a business trip and you are alone at home, so Hae Run returned home immediately after the university, when he came in, you immediately hugged him and you went to watch a movie in Hae Run's room, you were sitting on Hae Run's bed, and Hae Run himself was in the shower, he came out of the shower only in a towel around the pelvis, you immediately embarrassed and closed your eyes with your hands, Hae Run was amused by your reaction 'Aww~ Baby boy is embarrasssed?' Hae Run removed your hands from your face and raised your head so that your face is at the level of his body, 'Shut up and get dress up soon.' You rolled your eyes and you took his hand off your chin and turned away.
