I ship those two just like I ship TaeNy, but unlike so I actually think:

one, they’re dating;

or, two, if they’re not dating—I’d say it’s quite obvious Sehun has buried feelings for his noona. Those uncountable glances, stepping in front of Kai to be closest to her, waiting for her—the evidence is as clear as Baekhyun’s obvious stares.

Taeyeon may have sized him up and found him very appealing, but the age difference may have gotten the best of her judgement, forcing her away from romantic involvement with Sehun who had just graced the birth of his adulthood.

In DJ Got Us Falling in Love—that moment when he laughed as she did something, (did she bite her lip?) I could never break from my theory of perhaps it was Taeyeon flirting, or, she referred to something they did, or maybe even…something they WILL do after the concert. Maybe this explains why Sehun sticks around until she comes by, then attaches to her like a love-struck fool of a boy who must follow around his crush.

LOL. So I'm not the only one who thinks this way between the both of them...obvious is obvious.
