I heard a recommendation from someone on a chatbox, but he wasn't sure about the name of the manga. It's a shounen-ai, in case you didn't read the title.

• About a 2 guys that are together, but one of them keeps going after girls and parties, and the other one has to go and pick him up when he's drunk
• and does this a couple of times, until the other one gets fed up and leaves
• and the other one realises that he loved him and goes to ask him to get back
• Cant remember the name

So there you go! All the information I have on this series. Can you help me out?

Dangit, it sounds like Overdose (or maybe another of that mangaka's works, I have trouble keeping them straight), but that's yaoi, not shounen-ai. o.0

Yeeeeeeeeeeees that's the one, Overdose, thank you so much xD
