[Locked] Looking for specific hentai manga

It's about a guy living in the countryside who finds out his childhood friend/crush is engaged. He has sex with her in order to win her back but she doesn't give in. They walk around the old country town to have a walk down memory lane, only to realize that they were both perverts in their youths and practically did sexy things all the time. I think it ends with the male lead fucking the girl until she gives in and they end up going to college together.
