So that means he already knew about the stalker and vice versa so the stalker was likely targeting him in the first place to get rid of him and he purposely got injured and made it seem like he was "protecting mc" so mc would feel guilty and stay with him forever after he got married....um okay...and like others have said he'd probably faking the injury too
Idk how to feel cuz like yihan was already not okay given the marriage thing but even jinwoon in future blackmails him and all so I can't really root for either guy I just feel bad for hayeon
