Ok so I might be dumb...but Yuta and Seunghyun literally had a conversation about how "Seunghyun has never even had a scratch before" cause he's been untouched and undefeated. And now in the latest chapter we see this isn't true? He was literally almost killed by the gang that was attacking the golden pavilion. So why that whole conversation about his body getting a scratch for the first time when the mirror broke? Is this continuity error?
Second question - Seunghyun has said he was a virgin and that his first time was when he r*ped Yuta. But then he hasn't even internally denied (in his inner monologue) that he slept with the woman who gave him her card after Yuta accused him. At first I assumed he was just bluffing to Yuta, and he didn't sleep with her. But the other continuity questions have me doubting - like did he actually sleep with that lady?
Yuta's whole thing has been to make Seunghyun regret his actions by seeing how tragic Yuta's life/death is and feel guilty for not having saved him when he could have back then.
Seunghyun realized at the gas station that Yuta was "always" going to keep doing this, keep letting himself get hurt/put himself in danger (since Seunghyun had even told him those guys were really small potatoes he could easily wipe them out), as some sick fate Yuta's traumatized mind had him convinced needed to happen.
So Seunghyun is like fine, let's end this cycle, you'll never have peace while I'm alive if you're always stuck on this - and decided to remove himself from the equation by killing himself so that Yuta could move on. (Not that I believe he's really dead for a second - just discussing motives/intentions)
