okay lol i've been sitting on this one for a few days thinking about writing this as mistaken ivansua eventual ivtl but i think sua would actually vomit in her mouth if this happened and also they are sooooo sibling-coded to me LOLLLLLL.

they do spend a lot of time together (unwillingly) but are like pretty close as far as siblings go. it would be super funny if till is just like...so..is she your um. "is she your girlfriend" (reading their "intimacy" all wrong) and ivan is like. "vile (customer service smile) she is my older sister" and till prays for the ground to swallow him whole

i think that ivan and luka have a repellant magnetic field that keeps them from getting too close to each other so this would never happen lol but they do have delulu fans who see 2 hot guys together and...well. you know the rest lmao. idk that till would read it this way tho.

idk i just can't get my mind wrapped around the fact that no matter what AU sua would happily stab ivan for sport (begrudging affection for his misery) and luka barely cares if ivan exists ("thank god i'm normal" - except jk luka does not at all think he is the normal one, he just hates ivan's brand of disease) can my man ever get a win (no)
