If mc wants to really want to move on he needs to go away from everyone there every one there are unhealthy crazy for him. Hamin first give him signals after he almost died she still wants him and now when he confessed she now doesn't wants him. at this point they're going in circles. He need to move on away faaar away. Either join army or move from that country because no happy ending is waiting for him with that group of friends. one possible candidate is revealed to be hers some kind of psychological experiment and others I don't even want to talk about. If author wants to milk PTSD in Mc he should make more research to that because it's not that fast like some kind swing of magic wand he will suddenly stop suffering from it because he have "friends" with him it's not working like that in real world if it was like in real world in next chapter his next steps would be either railroad or free fall from tall building.
