Debut is in the unfortunate position of being genuinely bad, yet not terrible enough to have an ounce of camp value. Which is to say that the two 30-minute-ish episodes which compose the OVA set aren't the sort of thing you can at least find joy in by getting drunk and making fun of them with your friends. Instead they're slow-paced romance/comedy with simplistic, overly-sentimental messages about accepting heartbreak, looking toward the future, and remembering lost friends.
Each stand-alone episode finds the four main characters with dramatically different dynamics to their friendship. In the first installment, Aki is unaware of who Saori is at the story's beginning, yet in the second the two have been friends since elementary school. This might be frustrating to anyone who had an emotional investment in the first episode, but I suspect that if someone did, they probably have far bigger issues in life than Debut.
The characters themselves are the usual list of anime archetypes: The pretty, red-headed dreamer. The raven-haired serious one. The short, boy-crazy goofball. The charming but slightly clueless one.
The stories unfold just as you'd expect--with the exception of one marginally super-natural moment at the end of the second--where everything is wrapped up cleanly by the end. To define it as "light drama" might actually be an overstatement. The one positive thing I could say is that it's fairly mild on the fan service and probably an okay OVA for kids. Whether or not subjecting kids to Debut constitutes child abuse, however, is an entirely different matter.
