for regular i guess he will be devastated... someone who he thought understand him and his situation ended up rejecting his feelings... i think spamton will develope obsessiveness behaviors like stalking them and think of kris while masturbate or something and might even lead to noncon stuff when hes too desperate

for big shot he will defo try to bribe kris with fancy gifts and sweet talking, pestering them til they say yes. but if it doesnt work he might turn to more extreme measures... like kidnapping... he could not fathoms someone not wanting to be with a big shot like him... just insane rich people things...
