The Peninsula Begins with Making a Wish

My previous book was abandoned, so I wanted to try again. It's still about K-pop, and the protagonist, Lee An-myung, is reborn into a parallel world on the Korean Peninsula with a somewhat useful system panel. He encounters familiar idols and celebrities, getting to know them, perhaps even falling in love. There will definitely be more than one female lead; Taeyeon, Sulli, Yoona, and Lee Jin are definitely included. Others will be revealed later, such as Bae Joo-hyun, Park Ji-yeon, IU, Kim Seol-hyun, Lee Sung-kyung, Nana, Han So-hee, Park Cho-ah, Ahn Hee-yeon, Jung Eun-bi, Kwon Eun-bi, Song Ji-hyo, Jeon So-min, Ning Yi-tak, Kim Dong-eun, Shin Yuna, Hwang Ye-ji, UEE, Park Ga-hee, Seol-ah, and Bo.
