Where is the last piece? ^^

Hiho, I need some help. I'm looking for a yaoi or shounen-ai manga I read a long time ago but I can't remember the name.
All I remember is, that the main character was a glasses boy who ran away from home. Got robbed and stabbed, was found by a bar owner and worked as a translator in the embassy. I think his brother was searching for him. Something like that.
It would be awesome to get back what's missin' in my memories :P

Thank you
