Forgot the name of that manga

I remember reading a yaoi or maybe shonen ai, but i forgot the title. there were 2 childhood friends. One is older by 2 years, and he called himself "Hii-nii". The younger one is taller, dyed his hair and has piercing.. Both of them are so clingy to each other. I really want to read it again but i never found it again. I dont even remember the younger one's name. I remember the extra story was their parents worrying over their overly clingy boys and talking about their future like maybe their parents wants them to go overseas so they can get married, then their boys just declare that they're just started dating and the parents faces were "so all these times you're not dating??"

Does that ring a bell to anyone? I really want to read it again..
