I've read these story a year ago, and I'm still contemplating about some plot holes and plot errors. They might've been intentional, because maybe this story might come back, regarding the fact that the author officially stated that they will post more works related to this manhwa.

There are TONS of plot holes.
There’s multiple theories out there that eludes to the possibility that Sangwoo’s alive. The ending was very rushed due to the limited time LeZhin gave Koogi to work on it, thus she didn’t really have the time to explain everything that she wanted to in the story- leaving a lot of loose ends.
Like when they took DNA and hair evidence from Bum along with the knife and a swab of the floor from Sangwoo’s house that was never expanded on; along with the fact that the Uncle’s blood from the cut on his hand was on the same floor as well.
Koogi also wanted to give choker boy a backstory along with Sangwoo’s relationship with the girl from the beginning of the story but never got the chance to.
The way the story ended was really ambiguous and left a lot of loopholes as to what truly happened. Koogi would never intentionally emphasize something unless it was meant to be important- hence, theres speculation that Sangwoo’s death was staged by the hospital to get the public off their backs. If he did die, why would the police not be notified? Why did Yoonbum keep getting sent to the wrong room?And if Sangwoo was killed by the old woman, why was his room so easily accessible with no police present?
The doubting theory on his death was during the scene when Yoonbum finally got to “see” Sangwoo, he went into the elevator, and in front of him was a man in a wheelchair with an IV bag with burn scars on only half his head- the same side as Sangwoo’s. Koogi chose to emphasize this scene especially without giving us a clear answer as to whether or not he’s truly dead.
It may seem like he’s died at face value, but Koogi really stresses on details and their significance and maybe she chose to end it in a way that really left it up to the reader’s interpretation.
This was the most intimate BL story I have ever read, Jesus Christ. The yearning between two sides felt real that it feels like it was my heart being squeezed into pulp.
