I really don’t think that was Sangwoo’s plan, that’s only my opinion of course but here’s why I believe that Sangwoo’s intention was to kill Seungbae :
– When Sangwoo was fighting Seungbae in chapter 30 he was really aiming to kill…
He was swinging the knife aimlessly and EVERYWHERE, he was intended to kill seungbae and for Sangwoo that was the perfect opportunity to do so, the police officer who suspects him in his house..alone..investigating him without a warrant, he was basically in Sangwoo’s den, and I believe 100% that Sangwoo wanted him dead.
In this panel Sangwoo has already planned to kill Seungbae, he was thinking about the best case scenario and found this one perfect, after finding out that Seungbae is without a gun or a warrant, he sorted his thoughts out and came to the conclusion of killing him.
He meant what he said here, he knew no one would suspect him, he knew that killing Seungbae was the perfect solution and he was determined to do so
That look, that crazy look in his eyes says everything, he was in the killing mode, expecting everything to go as smooth a ever
That one right there makes me believe that Sangwoo wasn’t planning on getting arrested, he was caught off guard and the shock is visible in his eyes.
So long story short I believe Sangwoo was actually going to kill Seungbae without hesitation, he was to get rid of the only person who suspects him and no one would know about it, how perfect was that? Going to the police wouldn’t do him any good, and getting rid of Seungbae completely was better than pushing him away, the plan didn’t work but thanks to Sangwoo’s intelligence he is now killing two birds with one stone, he knows how to make the best of any bad situation (for himself ofc), he will get Seungbae fired shattering his image (more so), and he will get the respect from the police since he’s the perfect innocent civilian that he’s always been known as
