I remember searching through the Taeyeon tag a long time ago, probably almost a year and a half now, and seeing a long post by a girl written as an open letter to her. Basically, the girl was depressed, and her idolization really helped her get through the day. Apparently she would talk about Taeyeon quite often around people very often, and she wished she could show Taeng to her family so they would see what made her so special.
One line really stuck out to me:
"I wish we could meet in person and talk like old friends."
