He's probably thinking he's an adult now and his caretakers shouldn't be so involved in his life. Quite typical for someone his age I would say.
But I agree that is caring just enough. She should be worried, you never know what might happen.
Er I feel like as long as he still lives with his caretaker, they will be somewhat involved with his life. Does she know about the ghosts haunting him? I feel like that would be a factor too. But its been updating so slowly that I'm not even sure who knows what
I get it...but he lives with her. It'd be one thing if he had his own place. Obviously someone you live with is gonna be concerned if you start hanging out at someone else's place every day for several days. And I don't recall if he has any friends, so that would have even more questions to suddenly start spending time with someone a lot.
Seonwu hasn't been home in days because he's been sleeping with Sangyoon and hanging out with him constantly. I don't get why he thinks his aunt is caring too much when she worries about him for that, especially since it started so suddenly. Heck, it's kinda weird because he even notes that Sangyoon has been super clingy--heck, they just formally started their sexual relationship. So it's weird when he thinks his aunt is being too involved; it's like those people in a bad relationship who know it but don't like to hear it when people bring it up to them.
