IT'S Finally beginning....

I skipped a few chapters just to check if this really was the story i saw on printrest. And turns out the two that brought me here is JUST A SIDE COUPLE!!!! 😭😭😭😭

Omg somebody please help find this manhwa
The mc is a teacher, a primary school teacher (elementary? idk). 

He lives next door to a guy who annoyed him at the beginning. He was a really loud neighbour. The neighbour is the ml and at the beginning he didn't show his face at all! (He used hide it, by wearing sunglasses or masks)Then mc and ml starting hooking up i think. 

Oh and Mc is helping or atleast trying to help the ml get a high school diploma. 

Mc is a hitman, his "brother" is an asshat. But his dad looked after the MC when he was younger.  Oh and he used to be a child actor (wait was he? Or is that a whole other manhwa)

They have some "Uncle" who actually killed the asshats lovely dad. And ml saw it all happen and has been trying to tell the asshat that uncle fu** his face is a bad guy. 

Uhm oh some kid from the Ml class was coming home late because she didn't want to go to cram school, she didn't want to talk to anyone but got along with the ml very well.

Also mc has black hair, i think ml has blond.
MC's sister works in the entertainment industry (i think she's a manager... Not sure) 
I know this is  all over the place I'm just writing as i remember stuff about it.😭

OH MY GOODNESS!?? i certainly was not expecting that...

*sigh*. If only i have amnesia so i can  forget that this manhwa exists then accidentally find again this time next year

Tiktok brought me here! I'm nervous and excited 😆

I don't remember inviting a pair of crack addicts today ....they look insane!!!

I knew something was up with the blonds 😐

So this guy turned Veil into a druggie

Is there anything like this? That's not Chinese
