she is bad at acting her face stays always the same and I can see no emotions.
that's not true. Idk in which drama you're basing on but you have to look more into her in different dramas. she showed an happy and optimist girl in Good Doctor while she played a mature highschooler in Solomon's perjury. She didn't get many important roles but she's already good and I hope she will play more important roles because I love her, as hard that Kim so hyun and Lee Jong Suk.
tbh Tae-o is way too good for any of the girls in this series. None of them deserve his love, he's way too good…
As they said in the first episodes in the first season, while song-I's friend talked about him to her, he's the "first boyfriend" that a girl could have. exactly because he's the perfect boyfriend, he takes care of them so much, he would love them unconditionally.
