So in Chowon's perspective, he is only scaring them off because of jealousy, whether he unintentionally hurt those two it was still wrong to kidnap and interrogate them for his own convenience, but don't be mislead by Chowon's actions, he's not all to blame because it's partly Dojun's fault for not taking care of his wife and making him feel insecure all the time. Remember the scene where Chowon visited Heesoo's place? It was full of Dojun's pheromones! It's like making his territory and blatantly saying that Heesoo is his, which he NEVER done with Chowon. But in the end, it was an arranged marriage so Dojun was probably just putting up with them for the sake of connections between their families. Putting everything aside, I still think Chowon deserves happiness, aren't we all..
