The story is amazing!! From the beginning where they met until the last parts they really planned it out. Ill give out my 2 favourite parts. First was when the trio fought they rlly built up the tension before the fight and even had backstorys and such. I also like the love triangle i like the female lead getting jealous and insecure with the Main leads female friend and the break up was actually for the better it made Main lead be more focus on himself first and the female lead. As for the casting... ALL ACTORS FIT THE CHARACTER!! My fav character was the second female lead she was rude and elegant which you normally see in kdrama but she was rlly different!! I also like the ML alot he was nice not like bad boy stuff but a real human being and the kiss scenes was OFF THE CHART I TELL U!!! How the ml iniates the kisses and put feelings into it. DEFINITELY ONE OF THE BEST KISSES IN 2020. THEY SAVED 2020 FOR ME. For the ost, yeah it was good no need to expand it a bit more cuz they literally hired the ost kings and queens!!!
I would totally rewatch! I like the storyline mostly because its music, the jealous/hurt/insecure scenes of female lead (im a sucker), realistically being not good at something you rlly want to pursue (same sis)! Its a drama where you can relate to it.
