Ok so this manga starts presenting the "hero" of the story, who's a perfect dude who's good at everything. he's asked by his brother, who runs a company, to fix a couple of things on this VR dating simulator. he logs in and meets some of the charas he's supposed to be pursuing. he becomes interested in this specific chara because no one has ever been able to pursue him. As time goes on they go on dates while our hero also deals with a "glitch" or "hacker" who's deleting charas from the dating sim. by the end of the manga our hero has fallen in love with this exclusive chara, and this chara has fallen in love with him too. after the hero promises to bring this chara to the beach one day, they fuck in one of the houses inside rhe the dating sim, the hero disconnects and never meets this chara again, thinkin that it has been deleted. As it turns out, our hero ends up discovering that this exclusive chara was a college classmate that was just too scared to approach our hero irl. they end up together and i think they do go to the beach.
this is all i could remember. i did read this here in mangago.

it was a beta x omega manga and it went like this:
Seme (beta, long hair if i remember well) was in a bar when he was suddenly approached by a stranger, who offered him a job very well paid. When they get to his "job place" it turns out that his job is to take care of the strangers' brother, who's in constant heat since he was bitten and abandoned by his alpha. The omega lives with a dog and is always wearing a big long white t-shirt, which later on is revealed to be property of the alpha who left him. Time passes and I think the beta and omega start messing around.
One day the beta decided to take the omega out on a walk, which he had prohibited since the omega had to stay 24/7 inside his cottage. Fast forward to the end of the manga, if i remember well the alpha comes back and confronts the omega, saying they have to get together asap because he wants his baby or some bullshit and he even threatens the omega with a gun. turns out that the alpha needs a mate to take on his father's company so he plans on taking the omega with him as a mere token, but the beta will not let him.
Fast forward, everything has been resolved and the omega and beta decided to move together to London I think??? I dunno but to get away from the omega's home.
This is as much detail as I can give, please help

So basically this manga, i think it was a one-shot, is about a seme and a uke that have been in a relationship for some time now, even living together, but the seme decided to cut off the relationship thinking it's for the best. The uke accepts it. The seme keeps bringing girls to the house to fuck with them, but at one point the uke brings a man, the seme gets really mad with jealousy and after a quarrel they get back together. I think it's an old looking manga, but not too old, like an early 2000's manga maybe? Please help! ┗( T﹏T )┛
