You are Zia, Doyoung's little sister. Over the summer break your parents go away for a long vacation. You think you're in for a boring summer, left alone in a big and empty house, but instead your brother has other plans. He invites over his friends from overseas and the party begins. Mini-series, suitable for lovers of NCT and good writing. Mature content, NSFW, smut, swearing, etc. Enjoy!
