first of all I was so excited about this drama since it was on of my fav manhwa's adaption . the concept , actors , storyline , production everything is on the level , acting was pretty good ( Although it was debut project of some of the actors ) and the OST '' !! chief kiss !! ASTCO Couples Cameo was unexpected n I love it , ik they will change some of parts from the original manhwa, still hoping that they don't change too much coz the manhwa was awesome ( 10/10 ) , one thing that I don't understand ik it's drama but still they're students why do they have to wear so much heavy makeup , for example Yoon se heon' lipstick ( was too deep ) n for seo Do Yoon ( dyed hair, bracelets , earrings blah blah) I mean it's school not fashion show babe !!
