I would totally recommend this k-drama. The actors and actresses are so good at acting they're all good at expressing emotions, this is total masterpiece, I just finished watching season 1 and I will be watching season 2 now, I love all about this K-drama, the ending and the storyline and plot but I don't know my favorite character here is rang, even though how he try to change himself he will be the rang that is soft hearted, I really love him and all about this K-drama, I was angry because someone died, He sacrificed himself and I'm totally angry just watch it but I know my reason to be angry is not valid because I'm angry because I feel like they don't even care when He died, it's not the same like when lee yeon died maybe the reason is he caused many trouble and likely villain so they don't care and also I'm angry because He is happy now with His family but I know He still won't be happy because He want his brother to live because his brother died, maybe that is a good ending for Him, He don't even know also his brother because He is reincarnated after He sacrificed himself. I recommend you to watch this, at first I don't want to watch this because I thought it was boring but it was a total masterpiece, you must watch itโคโกโคโกโคโกโคโกโคโกโคโกโคโกโค, you will shed tears, laugh, angry and all the emotions.
I edited this because I will add my review for season 2, it totally heals me from rang and I feel that he got what he deserves. This is a total masterpiece, no boring episode and it will heal you because of all the friendships here and their happy ending. Must watch this
