I will never take recommendations from people who don't love mature romance/slice of life dramas, or the ones…
I agree. C-dramas are overflowing with Highschool dramas to the point where it feels overdone. These dramas would have been well-received back then, but now, people want to watch something fresh.
Wen Yifan is not a cold-hearted person. She is just protecting herself from past pain. Trauma affects people differently. Some will cry, and some will lash out at others. Then, there are people like Wen Yifan who build walls to protect themselves. Can we try to understand how trauma affects the way people act?
