Lost title

Hi, I'm looking for something I read a while back but dispite how much I remember I'm blanking hard on the name of the title and even the characters names

In a world of Nekos two men fall in love and eventually have kids themselves

The main character is a dull looking guy who is first introduced climbing out of a hotel bed and leaving money for the hotel fee and a note saying thank you after having slept with a stranger raw in hopes of getting pregnant.
Turns out he's an orphan who wants to have kids of his own and to raise them with lots of love since he didn't get any growing up.
He then goes and gets a lunch box and eats it in the park giving his last piece of karrage to a stray cat calling him "ancestor-sama" in reference to his neko genes
Main characters future love actually overhears this as he is napping on the next bench over.
Future love turns out to be a pure blood model.
MC who had been working odd jobs and trying to save lots of money for his future kids by spending as little as possible on everything else including his own food budget then gets a call for a good paying job - turns out this job is to be Future Love's manager.
Future love remembers MC from the park and demands that MC eats lots of karrage and from then on keeps trying to feed and fatten him up as well as cock block him by Insisting that MC cooks good food for him at his house and they go grocery shopping every week.
Eventually FL bangs MC and gets him pregnant.
Even though FL said he wanted to take care of the kids and raise the family together before knocking MC up, MC had convinced himself that these honest confessions were just sweet nothings and doesn't think otherwise until FL proposes.
The end chapter consists of FL coming home to MC sitting with his two cute babies in each arm
