So I can't find this manga. Hard working office small boy with glasses wants to be like is brother so he goes to the club and gets drunk, sleeps with a player like guy and regrets it afterwards. They see each other again when his brother wants them to be introduced. They later get into a relationship. I remember the whole plot (not complete story for it will take to long) not the name
