There's a guy named Kim Namjoon who's my cousin.

Kio and Namjoon were sisters by their mothers, so they were considered cousins. Later, Namjoon debuted in a boy group called "BTS" under Big Hit Entertainment... Kio grew to like all the BTS members (except Namjoon). Whenever Kio brought her two best friends over, Namjoon would always bring the BTS members over to Kio's house to visit. This is a story about three girls, including Kio, and seven idols, including Namjoon, having fun together!
