This drama is very similar to the first frost as the only difference between these is in hidden love it tells the love story of sang zhi and in the first frost it will tell us the love story of her elder brother sangyan this two drams are amzing and yes if you want to watch a fun light and hearwarming romance go with hidden love but if you want a darker a bit emotional story then yeah surely go with the first frost both of them are best in their own ways
