1. Korean fans suspects that there is something going on between Sehun and Taeyeon because of how Sehun not using the words "noona" or "sunbae" attached to Taeyeon's name. Fans have once heard Sehun calling her Taeyeon only once at an event. The reason for suspects is because being formal in Korea is a BIG thing and even if you're close to that person you must use it at all times. So by Sehun not using it, it's either Taeyeon allows him to or they're dating or getting there and plus in a relationship of dongsaeng-noona, if the the man who is younger doesn't use that on the older woman then that means that he's trying to show dominant.

2. The ones who are closest to EXO are Taeyeon, Hyoyeon, and Yoona.

3. Taeyeon and Suho both hang out with the same group of SM friends.

4. Taeyeon is closest to Suho, Kai, Sehun, and Chanyeol (in that order).

5. EXO fans wonders why Taeyeon chose Baekhyun whom she is closest in EXO when Taeyeon and Baekhyun never hang out.

6. Korean fans says that Sehun and Taeyeon makes a cute couple because there's something in the way they gaze at each other and for Baekhyun and Taeyeon, it's more of a noona and fanboy relationship.

7. Hyoyeon is closest to Kai while Yoona is closer to Kai and Suho.

8. Yuri and Tao are gym buddies but they don't go to gym together. When they see each other at the gym they hang out.

9. Taeyeon, Yoona, and Hyoyeon are the ones who hangs out with EXO majority of the time, sometimes Tiffany and Sunny would tag along.

10. Taeyeon takes EXO out to eat on multiple of occassions before.

11. Taeyeon would pay for EXO when she takes them out to eat and while the boys are waiting for Taeyeon to pay for the bill, Sehun would be the one to fight with Taeyeon over the bill to pay. A fan even witnessed this once...

She went to eat out at a restaurant near EXO/SNSD dorms, and this was after SMTown Seoul. So this fan was there eating out and it was around 12 midnight. Taeyeon, Tiffany, Suho, Chanyeol, Luhan, and Sehun were all eating together and when it was time to pay, Chanyeol said that Taeyeon should pay. After that, Taeyeon got on the phone with someone and told that person to hurry up, basically like bossed that person around and then she goes "KIM HEECHUL I SAID 15 MINTUES AN HOUR AGO" lol. So after the bill came, Tiffany said that Taeyeon should pay because Taeyeon is the oldest and then Taeyeon said that Suho should pay because he's the oldest guy. Taeyeon then pulls out her wallet to pay but then Sehun said something and so the two starts bickering and so Suho said that he'll pay but then Heechul shows up and he ends up paying for their bill. After everyone had gotten up from the table, Sehun got up and waited for Taeyeon to get up and then walked behind her. She was making silly faces to him while he kept a smile on his face. 

12. Taeyeon is adored by sane EXO fans and Suju's noona fans.
