A little spoiler :
This Pregnant Omega got pregnant by Ml's legitimate Brother. Who died by some accident , now he wants justice for his lover. And give his child a secure family.
This comes out as extremely surprising , the one who seeks justice has no problem making an Omega like him who did nothing to him getting Gangraped.
If he really wanted MC out of his business , he could have arranged some sort of escape route for him. MC would have gladly taken it .
Now look at him how he's any different from ml's parents .
Guess its Danmei for you.

Let's say we agree with researcher's words , ML is just a passtime . But the thing he called him personally to tell him that means he's not.
Why couldn't you have ignored him like you did with others ? He's just a sidechick right ?
Just admit it , he touched your nerve didn't he ? 〜(꒪꒳꒪)〜
Recessive is a special case. Not only to him but to you as well .
And That's how that forever Sleepy Kiddo was Born zzzzzzz
I thought the same he sleeps so much.
He's Literally made so that his parents can have sex.... Like, hey don't be so loud, your wake the baby.
The baby: zzzZ zzzZ.... *・゜゚(^O^)↝
