I just finished reading this manga

It's called Absolute Boyfriend. It's about a girl who has no boyfriend, though she really wants one. One day, she meets a weird salesman that she returned his lost phone to. He recommended she went to a website. She did, and ended up getting a human-like android as her boyfriend. They fall in love, but her long-time childhood friend confesses to her, and things get out of hand. In the end, the android expires and tells the childhood friend to take care of the girl in his place. Made me cry like a million times while reading it.
