I watched this when it first came out in 2016, now in 2022 I rewatch the whole series again. It still really is very good. Not easy to find a series which all the cast has really good chemistry together and all every single one of them fits their characters really well ! OST wise it is also one of the best ost album ever. The only thing is I wish Netflix or something will take up the drama and have a season for all the global fans , we need to have a season two for a closure but I know it’s hard to have a season where all the cast will be available because after this drama most of cast became even more popular
