Let's say Cheol did in fact chocked out Minyeong which led to Minyeong to become unconscious, so Cheol now thinks Minyeong is dead. This leads to Cheol attempting to commit suicide since he isn't that type of guy that wants commit violent crimes plus the title is Die in my Arms. Once Minyeong becomes conscious again, probably notices Cheol bleeding out, he starts to spiral again due since he keeps seeing Cheol on the verge of death.
Next obvious would be Cheol is simply hallucinating, which could lead to him having seizure since he doesn't know the difference between what's actually happening and what isn't.
