Okay, I'm gonna tell what I understand so far. So basically, our little twink had a trauma and mental disorder that is cause by the death of his family. On the day before all the accident happened, there is a big black cross on the building walls. The brother know what that means and tried to rubbed it off. I suspect that it means they hv been targeted by the Black Death. Soon after the building burned off and then the whole family got into an accident where he is the only one survive. It wounded him mentally.
Tera here is part of the Black Death, which is where Joris's brother is also. Both of them are friends. I think Tera killed someone in the past and had to run away, which Joris's brother follow him as a good friend. Then they met with Luc, after that they made the whole Black Death thingy. They stole money and giving it to the needy. After the business success, they need to pay it back to black death, that's how Tera explain it to our twink(i'm so sorry i forgot his name). But it seems that's not the case, since they killed the people they had business with. Like the person they burned in the rooftop and the burger(?) business owner one. I had a feeling that maybe the twink family is part of the business before or maybe they are rich enough and being targeted as their prey. So, in that theory, Black death killed the twink family. Which makes Tera feel guilty after that because before they talked about killing guys eith family and leaving scars to the orphans like it's entertainment for Joris's brother. After that he tried to warn the Pizza guy, their soon to be target.

Tera is part of the Black Death group that goes around making deals with people when they need money and when they can’t pay back they mark their door with a I think black cross but then he met the Mc (yk the one who’s scared of the dark) and he took an interest in him so he’s been spending a lot more time with him and he recently found out why he’s scared of the dark- so apparently the Mc was explaining how his family died, that one day “a black cross” was on their door and his parents were scared but he didn’t understand why but then later (that night or a couple nights later) their apartment exploded and mc was the only survivor but mc doesn’t know that Tera was most likely apart of that that’s why Tera was so frustrated when he went home and broke his mask and I think rn he is sort of considering leaving the Black Death but it’s not easy. (Yea I think that’s it ٩(๑❛ᴗ❛๑)۶)
Honestly, I don't know what's going on here anymore..
