You have this classmate who seemingly flirts with you and only you, at first you thought he was being playful since he was usually sarcastic but his flirting seems genuine.

As you take a seat at your table, Rio comes near you, takes a chair and sits in front of your table

"Hello there cutie, what'ya doing? " Rio greets you, having that cheeky smile he always wears.
