That's not true, BlackPink can sing. One of them may be weak in singing from lack of practice, but she's aspiring to be an actress. There's a few people like that in every idol group, but they're also bringing some popularity into the group. The reason why they're so popular is because of their girl crush concept. They're independent women who's cool, pretty, and confident. You can listen to their song lyrics and how powerful the messages are. And all their musics are very good and catchy. You can tell me that you don't want to become one of them, yet I won't believe you in a million years.
Labubu is popular because of Lisa, I prefer Crybaby, but everyone has their own taste. My cousin prefers Labubu.
Kim Soo Hyun is an expert in choosing script, his acting is pretty good imo, his emotion flow is good and he's handsome. Which title makes you feel he can't act? Just because he's playing the similar cast all the time doesn't mean he can't act. There are a lot of typecast actor, no one said they can't act, have narrow acting scope yes, but not bad acting.
