is hwon the beggar or the childhood friend?

**spoilers up until ch 24**

i'm so confused as to whether hwon is the beggar or childhood friend. they both have straight hair. idk about the mole thing.

evidence is:

in chapter 22 (near the end), childhood friend said "want me to beat the crap outta them, pull out all their hair and teeth, and make them shit blood?" because people have been bullying woojin. woojin replies with "wha? you planning on becoming a ganster?"

after arguing back and forth, woojin says he doesn't have a phone and asks childhood friend how he would find him. childhood friend says "i'll follow you without anyone knowing."

so, we know that hwon is in a mob and when woojin sleeps with other people, he beats them up and takes their teeth to show woojin. whenever woojin runs away, hwon would always find him somehow. he always know where woojin is and who he's with.

what we DON'T know is (as of ch 24):
- whether childhood friend survives being hit in the head
- the real face of the beggar
- how the step brother came into the picture and why he developed this obsession for woojin. we know that the brother supports his mom's crazy antics. we also know that the brother knows woojin finds people who looks like his brother to sleep with...but is that really true? woojin is such an unreliable narrator. when he first meets his hyung, woojin cries. there are two scenes with two different lines. either woojin cries bc he's stuck with a hot brother he can't like, or he cries because of the guilt of his sister and childhood friend. WE DON'T KNOW!!
- who woojin's father is/what he does
- how hwon knows how woojin's sister looks like/met her before. hwon said in a previous chapter, when he gives woojin a pill that's apparently "medicine," that woojin is prettier than his sister. the author also draws a creepy smile for hwon. in the end of the chapter, woojin doesn't hear what hwon said. this scene implies something, but i just don't know what. we can't be sure hwon isn't the one manipulating woojin. we don't know anything about hwon.
- when hwon really met woojin. hwon said it's love at first sight, but we can't be sure their timeline is the same. woojin is an unreliable narrator as his memories are unclear and he's not exactly mentally stable.
