Best teen drama ive watched and its only ep 1??!!

I have been a Korean drama fan since 2010 and I have watched almost all teen k dramas and this has been so impactful to me. Most Korean drama fans would also know how hard it is to survive in the kpop industry. Even BTS struggled before they gained fame and this drama and webtoon highlighted those parts really well with a sense of humor and touch of romance.
I enjoyed the first ep so much I have already watched it 5 times. I'm waiting for the next ep as well as more performances on youtube !!
