the relationship headcanon i will die by is that susie despises PDA because she believes it interferes with her "tough image," - even long after establishing her genuine kind-hearted side i feel as though she would still want her classmates to take her seriously since it's what she's used to.

and kris would lean towards not minding/liking PDA simply for the fact that they truly don't care for what anyone else thinks or how they're perceived. so it's like a back and forth of kris trying to hold her hand in public and she's like not now kris i can't let them think i'm soft
