The only reality tv show I watch right now is Ngôi Nhà Chung
It's a Vietnamese dating reality tv series. They are currently on their 12th season right now. In the show they have a group consisting of an even amount of males and females. They spend time together and do challenges to find someone they would like to date after the show. There's also a secret couple in there that has to pretend they're not a couple.
I have also watched The Face Vietnam
It's a modeling reality tv series. There are three seasons out already. I'm unsure if they're continuing this show though because the last season was in 2018.
