First, sorry for my english.

So, almost 3 or 4 years ago, i read a H manga about a guy who just broke up with his GF, then he found a girl robot outside of his house, bring her in, and activate her. Turned out, she's a robot specially made for him. For a year, she take care of his lust and all, and until one day, her battery runs out. He's take care of her (robot) until 1 year, the new update software for the robot came up, but it must reset all the memory on the robot. Bla bla bla cry intensifies and the guy recived an update without the robot forget all the memories they been trough, happy ever after and the robot deactivate herself when the master (the guy) died.

Please, what manga is that? i need the title! its my first H manga that made me cry!
