It's not as much of a red flag as the FL. The FL is toxic, selfish, mean, and a liar. She deserves everything…
Are we watching the same drama? LOL I don't think Zhou Wan is selfish, she cares for the people she loves deeply and sacrifices her own happiness in order to protect those she loves. Ex: Her grandma. There is no need to explain why. She broke up with LXX, because she agreed with his grandpa and what she thinks is the best for him. She thinks she was the unlucky star for him, hence she broke up with him. It's the not the best breakup, but seriously? Are we even watching the same drama? LMAO As I said in my previous comments, she is also a red flag, but she's definitely not selfish. As for being mean and liar, well obviously she has her reasons, but she's not inherently mean. Zhou Wan's character isn't one dimensional, it's practically three dimensional. If you think she deserves worse then it just means you don't understand where she's coming from and why she did what she did.
He is suffering from depression and taking pills for it. He also had insomnia before.
Depression doesn't excuse one's behavior towards another though??? It doesn't explain why he's so aggressive and forceful with her now. It's clear he's still hurt by the sudden breakup, and had no closure. He's doing this most likely to try to get her back or to see that she has some inkling of love for him.
I get it. But LXX is so annoying here cause he's doing it out of pettiness. It's clear he's still heartbroken and in love with her, bet Zhou Wan sees it as well. Meanwhile, Zhou Wan was using LXX cause she wanted to save her grandma, or didn't want to ruin LXX's future, etc. aaaah jdhaisbsj this drama is crazy lmaoo
omg I'm on ep 23, and LXX is a major red flag. He is giving me the ick. x.x Technically both leads are red flags for one another atp, but it's LXX's turn I guess.
Omg it just doesn't sound fitting to me T.....T I'M SORRY. i don't remember her voice being like this, I know its for the character but I didn't think it was this high?
