Woww Good move

Perez is so smart, he knows that Tia doesn't consider him as a man man, like she sees him like a project, kinda like a character and a friend, that is too the because of her never realizing his feelings for her, because she stills consider herself like a outside being like a reader

So the slow approach of his is the best for Tia to start realizing his feelings and that he is no more a kid nor a person that needs to be cared, and that she interferes in the future outside of things like politics.

I'm not sure if I could properly express what I was trying to say
