Did you happen not liking a member(s) of your favorite groups and after learning more about him/her, you started loving and supporting him/her?
Actually it happened to me with:
NCT Jaehyun, Taeyong, Renjun, Kun & Hendery
1. Jaehyun: I was a bit confused cause I had mixed thoughts about him, but after a while I liked him and I still do.
2. Taeyong: At first I was scared a little because of his "cold" aura in MV.......now? I just keep adore him and say: "NCT's mama is a baby to my eyes (even though he's older than me
).
3. Renjun: Same reason with Jaehyun.
4. Kun & Hendery: Same reason with Taeyong (Hendery is now my bias in WayV
).
MAMAMOO Solar
To be honest when I watched Egotistic (my first MAMAMOO MV) she looked so serious and a bit angry? I guess she did it because the song is
But after watching some bts(behind the scenes) videos or other MV she looked like a mature teenage girl
(It suits her though if you agree
). Now I love her voice and the way she take cares the other members! 
EXID Hani
Although Hani has a nice personality and I really admire her, before I enter LEGGO (EXID fandom) I was thinking that she's a bit overrated........it's true in some way, BUT now I support her as much as I can along with LE, Hyerin, Jeonghwa & Solji.
I can't remember anyone else for now. How about you?
