LMAO that is a real struggle. i think it would probably be a case of opposites attract unravelinf tbh, stef is the opposite of laid back and chill so i could see them being initially attracted to that difference in one another but i know she cares really passionately about ALL OF THE THINGS and she would probably get frustrated with him eventually for being passive and we can say it just led to them fighting and bickering all the time to the point it wasn’t even fun. maybe they were together for like 6 months?
