Tao has done the right thing, he had just let go of his everything, Sehun.

Then he met this arrogant, blonde, handsome, tall guy. Tao do not have the heart to check him out, or even notice the blonde's presence.

Until... the arrogant side of the blonde disappears.

And was replace by a very affectionate guy.

Now that Tao knows what he wants, this time he won't let go. He is sure as hell that he'll get what he wants. No more selfless Tao. He'll get him, that's for sure.
