While taking questions from fans, one fan asked Hayeon if she ever fights with Taeyeon.

And Hayeon didn’t hesitate before giving her answer.

No. Never. It’s not possible. We’ve actually never fought before.

— Hayeon

Hayeon hinted that she chooses to listen to her big sister for the most part, which prevents fights from breaking out.

If she tells me something, I just say, ‘Okay, Unnie. I’ll think it over one more time.’ We never fight.

— Hayeon

She then went on to describe her big sister as someone she looks up to and fawned over her wisdom.

Taeyeon Unnie is always right. Nothing good comes out of not listening to her.

— Hayeon

Hayeon, who is 9 years younger than Taeyeon, debuted last year with her song, “Eyes on You.”
