Is it just me

Um no what..
Jiwoon is just super worried about red head might hurt Suha again. That part when red head took Suha away from Jiwoon when red head tried to rape Jiwoon with some rapists. Suha said if he go to office he will meet red head which triggered Jiwoon coz he doesn't want Suha to meet with Jiwoon again. Red head said smh like this will happen which means red head seems like he triggered Jiwoon to become like this way. Jiwoon family also neglected him and only care about red head (Jiwoon cousin) everything made Jiwoon to the edge and he always feels anxious when it comes to red head

he didn't lock him up yet. here is where you wrong, he just stalking him a lot and told him to tell him when he is going out!!
he didn't lock the door or anything like that. where did you get that from?

I didn't mean literally lock him up. He's isolating him though, stalking him, taking his phone and lying about it, etc.

He's definitely not acting right and is walking a fine line better protection and control.

he isn't isolating him! if he did he won't have let him meet anyone at all in his life! he just stalking him! it is different!
he was like that from his childhood though ╮(￣▽￣)╭ a very creepy stalker. he isn't as creepy as he was in the past

Just read the other comments.
I'm not the only one who's getting suspicious of the director and his behavior right now.

Well it's not like he is bad guy or something. And also they have mutual love for each other. Suha also not against at staying home for work. I mean it's not like Suha hate the way Jiwoon acting and don't want to stay at home. Jiwoon is possessive and keeping phone is not right but we need to see what will happen in the future. There's nothing to suspicious since what Jiwoon doing is possessive literally. If Suha wants to go if he says that Jiwoon might let him go. But they both love each other

Now he actually is trying to lock him up.
