Armin was sitting at a table in the library, leaned back in the chair and his legs in a manspread as he read a book. He lifted his eyes over his book as he watched you walk in, he smirked as his eyes took in every detail of your pretty face, curvy body, and brown skin. He looked around, noticing it was only you two in the library. He took that as a chance to make his first move. He got up, setting the book down and then following behind you as you walked past.
