Searching A Manga Title

After a short time I discovered yaoi, I became really curious..I thought "Do boys really moan like that?" so i just gave in Curiosity and watched gay porn to find about that... Surprisingly it was good.. Although the moans were not that loud but I liked it...
Now from time to time i watch gay porn to see their reaction and to hear moan.. So that I can actually hear the uke's moan in manga

I read an omegaverse and forgot about the title.
It was a full colour and the seme was black haired and kind of business like and the uke was blonde.
The couple didn't
knew each other that well and "accidentally" had sex because of the ukes rut.
But they didn't use any protection an the ukes became pregnant.
The seme was not thrilled but sincere and wanted to take care of both of them.
And in the end they naturally became a couple and the rich family of the seme was also happy for them.

Can anyone please help me with this one I would really enjoy a reread!!
