Really? You never knew I stan RV?
I guess I haven't had an RV sig in a long time but I've said a few times on the forum about how/when I got into K-pop:
Long story short, I got into K-pop in early 2014 (I found SNSD, Apink, TVXQ, EXO, Girl's Day etc) and really liked them. But in the summer of 2014 when RV debuted they became the first group I "stanned". They've been one of my ults ever since. I can easily say Red Velvet is one of my most watched groups content wise (I've seen many of their variety shows and reality shows etc) and as for bias, I think it's the only group I can't easily point out who in the group I like most.
I'd say Yeri these days but only just lmao.

P.S: To put in perspective of how much RV content I've watched and why they are one of my ults, my content list would go like this: RV > Dreamcatcher > Apink > (G)I-DLE > then my other faves like EVG, BP, IU, Loona etc.
Question: Do you have sigs on at all where you can see other people's sigs? I've had Red Velvet first in my sig for a long time.
