Brother Next Door

Seoyoon meets a named user who impulsively uploads a one-night video on a gay app to give up six years of unrequited love. However, what appeared before my eyes was my older brother Dojin, whom I had a crush on. Do-jin, who has been leading a double life with thorough management, is discovered by Seo-yoon, who confidently says that he wants to be Do-jin's sex partner so as not to miss this opportunity. "Brother, do you hate having sex with me?"
