It's a yaoi manga.

The plot is about a high schooler who fell in love with his friends older brother which is his online friend, because his friend's family is moving. They started to going out, but suddenly, out of nowhere, his boyfriend is asking for break up, and he feels devastated.
Two or three years later, his boyfriend come back to the school and ask him to come back to him, and he says yes. They started living together and working hard to get an approval from the parents (the break up was because the parent found out about them going out)

Does anyone can help me with the title?
I am really appreciate this.
Thank you so very much.
