When they CONSTANTLY try to compare Winter to Taeyeon.
Ever since their debut I can't search Taeyeon on twitter without Winter showing up and it's getting real tired. I get that everyone wants their fave to be like Taeyeon and sure you are not alone in doing the "next taeyeon/taeyeons daughter" thing, but you are far and beyond the worst.
So please, if you're annoyed at the comparisons maybe stop comparing your faves to others too. After coachella many in Taeyeons solo fandom started to openly tweet about how pissed they are over it, so please stop before we get into fanwars over it. Let Winter have her own identity.
