[Story & Concern] Disgusting yellow-toothed auntieㅜ

I have a 10-year-old nephew.

While playing, we face each other and share a bright smile.

In an instant, my nephew gasped and said, "Auntie, this song is so good~ㅜ"

I was doing it. That moment was also very shocking for me.

I started to wonder if I should do whitening treatment.ㅜ

I can't smile brightly anymore...

I can't give up my favorite coffee, and the face of my shocked nephew keeps lingering in my mind. What should I do?ㅜ
