There's always a swali of how solo releases will effect group dynamics: will the other members be jealous au supportive?
Luckily for Kim Taeyeon, it looks like at least one member in Girls' Generation is extremely happy for her.

On Oct. 6 Girls' Generation's Taeyeon hosted a broadcast on Naver's "V" app in celebration of the release of her solo mini album "I." During the broadcast, fellow member Tiffany Hwang made an appearance via phone call. It was revealed through their conversation that Tiffany cried when Taeyeon finished recording "I."
Soompi reports that the conversation of crying came about when Taeyeon brought it up jokingly.
"When I finished recording and played the final version for her, she suddenly started crying," alisema Taeyeon.
Tiffany then clarified how she felt when she first heard the final version of "I."
"I was like a faucet that suddenly turned on. I don't cry a lot these days, I'm strong. But I'm not lying, when I heard Taeyeon's song, I was crying for like three and half au four minutes," explained Tiffany.
According to Taeyeon the crying was contagious because she started crying too, and then the rest of the Girls Generation members became teary eyed. Tiffany became moved to tears once again after Taeyeon thanked her and the rest of Girls' Generation for all of their support.
