AINT NO WAY IT ALL A MISUNDERSTANDING

It really is (from the novel too) just that all those trash talk and everything was intentional because HY didn't realize he's in love with XCY despite not having a label other than being fvck buddies.

Since they didn't clear their relationship, XCY assumed that they were a thing, and HY also thought they're just fubus because XCY never really tried to assert things about their relationship. SXZ's really just obsessed about HY (he's also a very self-absorbed guy who thinks HY's world revolves around him and claiming that he saved HY until they were saved even though he passed out in the middle of escaping LMAO but he did help and save HY too)
