Alright just finished the first two episodes of Heirs, I don't know it might be because I've just finished watching Good Doctor, The Masters Sun, and Two Weeks but Heirs seems a little dull and maybe a bit boring in a lot of parts. I won't write it off just yet though because it's still early on and I love the cast. I've seen comments that have said it reminded them of Gossip Girl and for me, since I've watched GG and I'm currently watching Heirs they are a bit similar minus the dirt poor main girl. Though from the sound of it, I think I might be loving the OST for this drama <3

A little bit about what I think of the charcters so far. 

Lee MinHo {Kim Tan}-  Don't know really, haven't gotten a feel for the charcter yet.

Park ShinHye {Cha EunSang} - Same as MinHo/Tan ^

Kim WooBin {Choi YoungDo} - Gorgeous piece of bullying douche.

Kang MinHyuk {Yoon ChanYoung} -  Love him so far {might be my biasness for the cuteness of MinHyuk} might change later though.

Krystal Jung {Lee BoNa} - Looks like Krystal got a role that Ive seen her get in muliple fanfics aka the overly jealous brat.

Kim JiWon {Rachel Ryu} - I just don't like this girl so far, from the first time I saw I had a distaste for her

Kang HaNeul {Lee HyoShin} - Didn't see him enough to know, he's cute though.

Park HyungSik {Jo MyungSoo} - He's just a y piece of cuteness that is probably going to be my light in this drama {Plus ChanYoung}
