Awww Heonjae :'((
Other inmate accidentally triggered his trauma about the Gym Teacher and his crime.
Heonjae freaked out because they brought it up in front of Myeong-il, which he never wanted him to know.
He runs out and hides, Myeong-il follows him and tells him it's okay and calms him down ("This isn't you" ahh type shi "I can fix him" moment is here).
Character arc progression for Heonjae because he just got some reassurance that Myeong-il won't leave him for what he did in the past.
So, I'm pretty sure after this Heonjae will... DEFINITELY NEVER LET GO OF MYEONG-IL NOW XDD jkjk (or am I?)
(Also, we were blessed with hot Jingi with an undercut again for ONE panel this chapter).
(But why were Myeong-il's eyebags stressing so bad the whole chapter? Cuz he didn't get to sleep that night or is he actually very disturbed right now??).
(Btw how did Heonjae cut the guy's legs? With a saw? With an axe? With HIS BARE HANDS?? Like a bear!!? A white-hair polar bear that looks cute but can rip your legs off!?)

Hold on... the labeled VHS tapes are what the prison uses to record prisoners each time there's an incident.
Jingi over the span of 10 years has tortured a bunch of inmates which gets a video recording each time.
So you're saying they send those videos to the creepy Uncle? The videos of Jingi doing those kinds of things?? Not to mention a bunch of those inmates look like the Uncle on account of being fat pigs??
Are those f*ckers recording Jingi for sick and freaky reasons!!?????
Why does Jingi get so scared seeing the Uncle and asking to cut Jingi's hair!? (Chapter 18)
I hope Jingi gets his revenge >:((

Rather than Myeong-il "reading" the letter, I think what he pulled out of the envelope was a picture instead. A very disgusting picture of a very disgusting crime.
It's a photo, because in the beginning of chapter 34, there's a flashback, a memory from the Noona. It was Jingi asking her to print some photos for him. Not sure if the Noona knows what's in them herself cuz she can't see it, but it seems like she knows it'll help Jingi.
Back in chapter 20, when she receives Jingi's correspondence, it said "Please send the thing on the 5th", she knew it was Jingi and what he needed.
So conclusion is that, Jingi has some dirt on someone. Evidence. Photographic evidence. And that someone is probably the Uncle. Jingi needs these photos for when he gets out and it's his turn to put the Uncle in prison.
So back to now...
Myeong-il opened the letter, saw the photo, and was instantly repulsed. Discovering that THESE were what's inside the letters Jingi wanted so badly. Myeong-il is now probably assuming things about Jingi. Not knowing the bigger plan at hand.

Uhmm, I just now noticed after re-reading. There's this mysterious new prisoner they were slightly showing the uniform number of in one of the panels??
He has glasses and was shown in the background then a close up of his uniform in the lines "When we went out last time...it was snowing... " and "They all went to get their haircut."

Also my theory includes the group of inmates myeong-il gambles with bc they’ve been seen at times looking at jingi and observing his behavior (them saying Jingi was quieter than they thought in chapter 40 and to wait and see how Jingi will act)… which is super sus. Almost as if they were given info on him beforehand to form their initial stereotype/impression of jingi

Jingi tying his hair into a bun like that was so hot I actually almost ca---
So, anyways. Latest chapter was mostly about sex. Jingi railed Myeong-il so hard his peanits can be seen bulging out of Myeong-il's belly it's almost impossible. And that c*m shot panel inside his ass was very... unique. I don't think I've seen other BLs draw it like that before.
Lol the best friend has a better sense distinguishing between the brothers than the FL has.
She's been hanging out alternately with both twins this whole time, but her friend can tell them apart better :P
