mm. this is a hard question! honestly, i think there are a lot of things that till does that piss ivan off, but ivan’s retaliation is usually being annoying in return, so it’s not easy to tell.

i think they have a lot of misunderstandings in the realm of feelings and expressing them effectively. i talked about this a little bit [here], but to recap, i think ivan is very caged about his emotions, to the point that he lies to himself about which emotions he’s feeling when. (his wires get crossed etc.)

the main thing i think till could do to piss him off is belittle ivan’s feelings (when they’re already in a committed relationship) because “i might not show it (the way you expect me to) 100% but i’m obsessed with you” — and, of course, ivan simply can’t say this lol. he would ice till out instead and wait for till to apologize and sigh and forgive till because he loves till. ivan is just hard to read. (on purpose, at that.)

i don’t really know outside of that tbh…it’s less “angry” that annoyed. till doing something ridiculous “damn that guy is dumb as fuck, i need him carnally” is usually ivan’s default. to me. hahaha
