Venti is in love with you almost to the point of madness and does not even hide it. he always follows you around and gets very upset if you don't give him "proper" (read as all) your attention. he just needs to be near you, as if without it his whole life loses color.

"Little flower? What are you thinking about? You've been all quiet like this for five minutes already, hehe~" Venti asked, swaying in his chair and admiring the view of you among the library shelves.
