Like u said ML might sus but he didn't pass boundary. He just ask MC that he want to walk him home for safety sake but mc decline his offer didn't he? For such small reason or ego? Despite that the fact he just experience horror?
His behaviour is unreasonable. Even u say ML is sus. Normal ppl will still accepted the offer. Safety come first. Also ML identity is clear, they on same school.
Confuse? Maybe yeah for the origin why ghost been chasing him. But if i was him, if i being target by ghost and i can be safe if i near that guy and he willing to help me. why not? we only walk home and sharing cpntact just in case for danger only. its not bigdeal. It just small price for a safety i got. And i can do research why the ghost target me.
I'd argue he's crossed several boundaries actually they aren't friends they're strangers they literally just met like a month or two ago and the extent of all their conversations has been the ML screaming at Jaeyoung for living his life and not heeding the whims of a complete stranger who keeps insisting he do xyz with the vague explanation of "it's for his own good" while also not explaining anything not to mention ML and Jaeyoung are the same age this isn't an adult trying to take care of a rowdy teenager and keep them from danger this is a strange classmate forcing his way in to his space and his life with no explanation and from his perspective putting him in danger
You say that we don't know if the ML is the root of the problem but we also don't know that he isn't or rather Jaeyoung has no way of knowing that he isn't especially because all this stuff only started happening the moment he showed up nearly right after ML shows up to Jaeyoung being frankly off putting and weird glaring at him who is again a complete stranger then the ghost or whatever they are showing up
Not to mention Jaeyoung's life is in danger suddenly not ML and instead of treating him like a person ML insist on screaming at him for everything he thinks he's done wrong when he has again not explained anything Jaeyoung's reaction is reasonable
At this point at the story Jaeyoung has been attacked screamed at criticized basically stalked by his so called protector and overall been treated like shit he has no reason to trust the ML beyond knowing that the ghost maybe don't like him and the only reason he's cut him off now is that the one thing he can supposedly rely on him for i.e. making sure the ghost don't hurt him he didn't even do so why the heck should he be nice and accommodating to this boy
It's kind of weird to me that people are calling Jaeyoung annoying or insufferable for not knowing how to deal with the random supernatural entities threatening his life and the guy who seems to be the root of the problem who also keeps saving him but also keeps treating him like he's stupid for not knowing what's going on I feel like his reactions are perfectly reasonable he's scared and confused and the one person who seems to have all the answers also refuses to explain anything to him and is being cryptic and quite frankly creepy considering he a stranger at this point keeps insisting on Jaeyoung staying by his side while also getting angry and snippy with him when Jaeyoung acts like a person with free will instead of a doll he can move around and protect it's weird and I'd even go so far as to argue that him blaming Yihan is also perfectly reasonable correlation doesn't equal causation but if you only started experiencing life threatening events after the clingy new kid started forcibly hanging around you and he refused to explain anything who would you blame for this situation
