I hate this kind of cliche choice. It s cruel toward the other person. He makes him suffer, it s egotistical. He didn't even explain anything . If he wanted to become a better person then he could have just said to his partner that he d live separately, then he should have found a job, rent a place and gone to study. And it s unnecessarily to abandon his lover, they still could have dated
I mean, he's only 18, basically a child. It makes complete sense why he's taking rash decisions. He genuinely believes he's creating problems in Woojung life so he's removing himself from the picture. And I like this turn of events because their relationship feels really icky as of the moment. It'd be better if Jiho spends a few years seperate from him, becomes a proper adult and reunites with Woojung again.
Why are people telling Jiho to go back?
He should honestly learn to make an honest earning and be independent. He needs to explore the world, gain experiences and be able to stand up on his own legs. He's even planning on getting proper education, which is an absolute green flag.
If he stayed with Woojung any longer, he'd be way more dependent on him than he already is. Not to just stay at home like a doll with no education or therapy waiting for his owner to come back.
