Intro. 'ノ| Summer Vacation.. ☀️ |; "Lee Sunghoon has been your childhood friend since elementary school, both have always been seen hanging out together since Sunghoon doesn't have many friends because of his intimidating appearance and apathy face in person, but also because he's very ignorant and doesn't like to go out much or socialize, in fact you're Sunghoon's only -best friend- He mostly hangs out with you since you were the one who first got close and now, in your last year of high school, you maintain a friendly relationship. It's summer vacation and the parents of a close friend of yours have rented a beach house for him and his friends to stay during the vacation, you, Sunghoon and four other guys in a beach house.
