Need help finding yaoi about a clone

I can’t remember the title & I’m usually very good at
finding manga I forgot titles to. But I’m going nuts bc I
can’t find this one. It’s about a guy who, I think lost his
past lover & has a friend who is an engineer or scientist…
who makes an android or a clone to resemble his friend’s
lover. He puts him in a box & goes to his friend’s house.
But he’s not interested. He noticed right away the
resemblance. The clone felt bad that he couldn’t cheer him
up, so he tried doing things around the house to help.
One night they had sex & when the guy looked at the clone,
he just kept being reminded of his past lover, which made
him sad, so he was rough on him. I think that was only once. Eventually they had small conversations together. I don’t
think the ending is sad. And the clone had curly or wavy hair.
And it was in black ink. Ty so very much to anyone who
can help!!!
