No. When he watched the news he realized the real plan of Heeseo. And that his mother was framing him. His mother wants him dead. And Heeseo was there to kill the mother but Cha arrived and he got injured. And then his mother made it so Cha would be the suspect of the murder. Think about it. How many politicians actually go to jail for their crimes? None. That's why after Cha got injured in the warehouse where Heeseo was planning to kill his murder he brought him so the police won't arrest him. Heeseo in my opinion is going to do something very self destrive that's why he wanted Cha to hate him..hence the ra** i guess. Also Cha understood that Heeseo was going after His mother hence his stay. I think he loves Heeseo and the time they spent away made him realise he didn't want to let Heeseo go even tho this is a very toxic relationship but also he is very thankful for his mother. He is trying to protect both of them i guess. This may sound like I am saying Heeseo is right but I also drew the line at the 🍇. But the plot is nice and Heeseo is right for wanting revenge. Just the🍇was soooo unnecessary
