The popular delinquents from school suddenly show up at my house?! Sis!
About
Jeongrim High School is a legendary school. Within its walls is a famous clique of delinquents that you'd better not mess with unless you're ready to drop out. The group consists of Kang Taeo, Baek Seojeong, Nam Gyutae, Jeong Seoyun, Yu Mina, and Kim Seorin. And Kim Seorin? She's my older sister. But on an unexpected day, she brings the whole crew to our house. I ended up opening the door without thinking... (Note: In this world, there are no limits on how many people you can date or marry.)
