What Mr Bae did was understandable. He didn’t want someone who he cared about (and clearly loved) to see someone who abused him. Yes, he should have talked to Yoo, and it was silly of him not too. But he didn’t want to put Yoo in a situation that could be traumatic. I wouldn’t say he was stupid but it definitely was a silly thing to do. His heart was just a little too quick for his brain. Because he cares so deeply for Yoo.
This story was never meant to be serious. It was just a funny story and I think it ended in a really funny way. It also leaves things up to the imagination of the reader whether Shion sorted out his issue or not.
