I'm starting to think he has bpd

I don't think so. The boy just likes her and he didn't have a good childhood and he is running from smt. He has compulsive thoughts or let's say inner voices originated from a trauma . I'm afraid he will obssess over Mc and may want to keep her in the banker with him like a prisoner but I hope author nim will not make this sad or toxic. I wish to read smt a lil bit balanced where Ml and the other boy become friends while he overcomes his trauma and comes to be the Mc's strength too. I mean she is hurt and lonely too

I meant the hallucinations/ hearing voices not just because he's possessive

i think that’s more aligned with schizophrenia than bpd
