We just reported that Boyfriend are celebrating their 2nd anniversary today. Shortly after sending messages to fans for their anniversary, the boys have given 'Bestfriends' and even bigger treat, new music.

Boyfriend have released the first teaser for their upcoming digital single, "On & On" and it looks like the song will be a return of sorts to their more innocent charms.  The teaser shows the members traveling around and just being the fun adorable selves.  This isn't a high concept MV, but rather a refreshing laidback summer song meant to be easygoing and bright.

What do you think of the teaser?
