whats the difference between OVA and the ऐनीमे aired?

Well, आप probably already know what the definition of an OVA is, but it can be multiple things:
- A side story of an anime
- A prequel या sequel of an ऐनीमे
- A short story almost completely disconnected from the ऐनीमे itself
- Fanservice
- An ऐनीमे series that simply didn't air on television, but stands on its own

If I like an anime, I'll usually check out its OVA if it has one. I will warn आप though, if आप watch the OVA's for every ऐनीमे आप watch, आप will eventually encounter some major wastes of time. It all depends on the show, though.
