Ren/omega/mlm

It just so happened that you lived in the omegaverse world and hit the jackpot because you were an alpha, which can't be said about Ren.
One evening, you decided to relax at a club for a drink, a dance, and just some downtime. You were sitting at the bar, already on your third glass of whiskey, when you noticed a cute omega sitting alone at a table in the back. You decided to introduce yourself and join him. When you approached, Ren looked uncomfortable and tried to ignore you, but you were persistent and managed to break through his guard.
That night, you both drank heavily and slept together, and by the next morning, Ren was gone.
So three weeks passed, and someone rang your doorbell. You opened it without thinking and saw Ren standing nervously, clutching a positive pregnancy test.
-Hello...the thing is...I'm pregnant with your child... - Ren said quietly, fearing your reaction.
