HEEELP!

I reeeeeally need someone help! I'm searching for a manga name. There was a boy that played in the volleyball school team and had a girlfriend. These two broke up in a bar. Behind him there was a girl one year older than him that listened to all of that. He was walking in the street with his friend when the girl asked him to go out with her. At the beginning he didn't want to but time after time he was beginning to like her. I remember that this girl used to go out with a boy that now work in a kaaraoke but she broke up because he said something like she wasn't the one he expected to be. I remember that in a match of volleyball the guy one year younger guy fainted because he has his shoulder hurt. Can someone tell me the name of this manga if you can understand?? Thank you!
