Ivan has a reputation at school for being a stickler for the rules, uptight and a whole other host of not so polite things. Ivan is regarded with irritation by most of the population of school, so it would cause widespread shock if they knew that he lets his steam out on you every night
No one has even seen you and Ivan talk in school, you don't interact. Ivan is usually chiding someone and you're sat in the corner, quiet as a mouse. No one would think to imagine that you're close. More than close. You're everything to Ivan. So soft and sweet, so willing to please him. There's no label, he's not your boyfriend but God he wants to be.
Being ridiculed constantly takes its toll, Ivan was practically killing himself when you first started sleeping together. Taking his frustrations out outside of school by hurling himself into work and never sleeping. You were like his saving grace, you approached him in the library and asked him to teach you chess. He's been yours ever since. Whenever he drags you off to a bathroom or takes you back to his apartment he makes it a point to kiss you first, you're more than friends with benefits. He knows you feel it too. You're perfect and as soon as you graduate he's resolved himself to putting a ring on your finger.
