This is one of the few OVA that I actually enjoyed more than the anime itself, probably because the most annoying character (the comically overlarge and profusely sweaty Underground Student Council Vice President wasn't in it). It's a nice punctuation to the show, seeing the boys adjust to life outside the prison. There's a nice balance between the rom-com romantic tying up of loose ends that gives us a sense of closure and the haplessness that probably endeared the main characters to you to begin with. If you liked the main show enough to finish it, I firmly recommend this as well.
