I'm trying to find a yaoi manga I read recently (month or so). I can't remember if it was just a one-shot or not but basically:
Main character loved his best friend but couldn't handle it anymore so he disappeared on(after?) their high school graduation day and cut off all form of connection.
Forward to 2-3 years or so and main chara is working and his friend walks into his work and is pretty much like "omg yay it's you! It's been 2(3?) years sINCE YOU LEFT YOU--" etc.
