Looked it up: Bilal works in a cosmetic company. Simon is the son of the guy who owns that cosmetic company. He's part of the story since episode 88, so pretty recently.
From what I understand, Bilal saved Simon from an homophobic attack and brought him back to the flatshare where he lives.
No dialogs in this video, just an agression. TW homophobic attack.
First video translation :
Simon: I wanted to thank you.
Bilal: What for?
S: I heard you talk with Marilyn.
B:...You're welcome, I guess.
S: I'll pay you back the rent as soon as I get a job. I don't want to outstay your welcome.
B: Everybody likes you in the flatshare, take your time.
S: I like you too.
B: What are you doing?
S: We like each other, right?
B: I gotta go, I'm late.
S: Bilal ? Wait-
Second video:
Bilal: I'm not gay.
Simon: You're not, I know you're not. Not even a bit, a little bit ?
B: ...
S: Just a tiny bit gay. A tiny bit. Tiny.
B: No. No, no. Sorry.
S: Shit... Such a shame! ...And I made a promise... Can't happen.
And they kiss
