Sebastian who never cuddles with girls but lets Jade curl up with him in bed because it’s not like she’s his girlfriend.
Jade sneaking in to Sebastian’s house even when he’s not there so he comes back to find her eating plums on his couch or doing equations on his floor or curled up in his bed.
Sebastian being the one person Jade can actually stand being around, who is a source of comfort to her, even if she would never admit it.
Jade helping Sebastian in the subjects he’s having difficulty with, because she might go to a comprehensive, but she’s smarter than any of the boys at Eton.
Sebastian telling Jade about his dates and pulls because he sees her like one of the boys, until it starts to feel weird, like he’s betraying her.
Jade making jokes and giving him advice at first, but then becoming quietly very jealous and possessive over Sebastian, but she doesn’t say anything because then he’d think she cares about him.
Sebastian and Jade basically being 100% a couple without kissing, sex, or acknowledging it, until Jade finally stakes her claim, because Sebastian has been her boy from the start.
