Ok... First of all, this chapter was AMAZING! I got chills from start to finish!
Second, I really loved Young-Woong's flashback. It gave a lot more contexts to what was previously shown to us in chapters 35-36. What a messed up individual he was... But I would be lying if I said I don't appreciate him as a character. It's really crazy how all these tragic stories intertwine with one another.
Also, can we talk about Maria's flashback? That person with the scar she was supposed to fight... Given her expression, after he revealed himself, it has to be a relative of hers.
He looks oddly similar to her and has burn scars. Maria's relatives and friends were killed in the fire caused by Jitae's father. so maybe, just maybe, he took some of her father's disciples with him and the school had them go through with the same procedure as Young-woong.
Now, the doctor performing the surgery called Young-woong a "failure" so it seems he got experimented on
in contrast to the regular Fight Class 3 students. Young-woong didn't earn a spot in Fight Class 3 so my guess is that he was sent to that doctor as a test subject.
Also, I'm really intrigued about the connections between the school and some of The Tunnel's factions.
Props to the scan group for their tremendous work on this release. Can't wait to see where the story goes after this chapter.
