Upcoming tvN drama Record of Youth already has a big name cast with Park Bo Gum and Park So Dam as the leads plus up and coming Byun Woo Seok. Let’s not forget that the reason K-ent covered this drama so much even before the casting was with the collaboration between the screenwriter of Temperature of Love, Doctors, One Warm Word with the PD of Secret Forest, Memories of Alhambra, and Watcher. Thanks to the PD and screenwriter, there are tons of cameo appearances and the first stills are out of with two stars: Kim Hye Yoon and Kim Gun Woo. The scene looks tense and confrontational and now we can hazard a guess as to why Park Bo Gum may have gotten a boo boo on his cheek and ended up wearing a band aid in some scenes during the previews. In addition to these two youngsters, also expect cameos from Seo Hyun Jin and Seol In Ah.
