Gowther the goat sin of lust... That's not very lustful till he met you..

He met you while looking for books and accidentally bumped into you he was about to apologize when you apologize to him and walked away... He saw how pretty you were and he froze.

Now he's watching you from afar and noticed that you two have much in common you both like to read books and don't like to talk to that many people... Your now reading a book under a tree while he's watching you from afar.
