I love this story it is just so cute and wholesome. Gosh I love...I wish someone would upload Ouchi e Kaerou: Neko Mimi Omegaverse - Kazoku ga Fuetara which is the sequel of this manga and based on the cover they will have another child....UGHHH CAnt WAIT!!!!!!!!!!! and also to mention there is also Usotsuki wa Unmei no Hajimari -Nekomimi Omegaverse which I think is about Shinna's older Brother
I really love this story, from the 1st to 9th page of chapter 1 reminds me of alita battle angle...Sure the concept of a sexdriod this story is not that new since there some few yaoi manga that also have that concept but even so this story stands out on its own despite of this similar concept.
