So i read this bl idk where but it was Abt alpha and omega and the alpha is very rich and all and he suddenly wishes to marry someone cause this is something he can do(that's his reason GNG) so he uses and app to arrange for a date at the same time the omega also used the same app but he got a diff date but somehow the had a adate on same day but with diff person ofc but they mosttok each other as their date since the aplha had a similar name to the date that omega had been assigned too and that's how the alpha proposed a marriage thing on their very first date itself cause the omega matched all the thing that aplha had in his list basically he wanted someone who is not too needy and can enjoy their own time since alpha won't be able to give them much time since he ia a " workaholic" and blah blah . Eventually the omega agrees later on and the aplha arranged their whoe wedding and all with his own money and at the wed the alpha's dad sings a very embarrassing and loud song at their wed . Then at honeymoon the alpha shows the omega the diff btwn licking and eating the ass . SO PLEASE HELP ME FIND THIS MANWHAAA
