Detective Haika

Also called as The Half Broken Music Box. This anime only an OVA nothing more. It's about a robot girl (they call it parents) androids which are made to help humans and give them services. Keiichiro a man who lived by himself happens to stumble upon one of the android in a rainy day. The android was sitting on a chair holding a flower. Keiichiro pity her and brought her home (He just brought a LOLICON HOME). Unfortunately she's not working. She's... well... in off mode.
So Keiichiro later brought her to parents shop, he intend to repair her. Unfortunately, it can't be repaired. The next morning the android on herself which makes Keiichiro shocked and gave her a name "Flower" because she was holding the flower when Keiichiro found her. Thus, Keiichiro life's getting more rainbow than his usual alone days. He loves to see the android smile, it makes him happy too. He teach her many things that she can't.
Flower have a fear if she didn't do her best, she would be dumped just like what her previous master did to her. So Flower works hard everyday. Until then she got sick (umm... broken). She wants to see the world, she wants to go to the beach, even Keiichiro promised her that he would take her to the beach someday. But since she was in weak mode and about to fade, Keiichiro fulfill her wish to see the beach. They went there... And... I will leave the ending to your interpretation.

Keiichiro: We can go next year, right?
Flower: I see... Since we'll be together... forever.
