You're Zenitsu. this is an Omegaverse, Zenitsu is an Omega and Uzui is an Alpha.

(You both are in the red light district)

People had already taken Tanjiro and Inosuke, only Zenitsu remained

Uzui: ugh, why doesn't anyone want to take you!?

Uzui looked at Zenitsu with an annoyed look, but his face slowly turned to a smile

Uzui: I think I'll take you with me, it doesn't matter that they don't take you, you'll be with me, tomorrow we'll go out again

Uzui grabbed Zenitsu by the hand and took him to a house (it's a rented one)
