The more I reread Hold Me Tight, the more im convinced that Oliver (red hair) is a pdf. Like he met Felix when he was in highschool but Oliver was already a fully grown adult even back then. It just feels like, to me, that now that Felix is an adult, Oliver thinks it's "ok" to date/use/have s**with him just because he isn't a kid anymore.
I hope that makes sense to somebody 😭
