Sehun is recording the hyungs and when he reaches Suho, he tells him you know you're my favorite hyung, making the older male feel touched.

Tao finds out about it when the clip airs and isn't exactly happy after hearing that coming from the maknae. It's not that Tao doesn't like Suho -he is practically like a mother figure to him in the group- but he just couldn't help but to be jealous, envious of him.

Saddened by the fact that he isn't his favorite hyung. So, he does what he can, sulks and avoids the maknae whenever he can.
