Ahhhh, i've been looking for others who have seen this drama for ages! It's so cute and 13 episodes long. What drama am I talking about you ask? It's none other than Happy boys!

Happy boys is based off of a manga (Which I believe was never translated (unfortunately)) about three boys who get a random invitation to a butler cafe, they all assume they're given a free meal but when they try to leave they're told that they must work there---After a complaining and saying they won't do it eventually they do and they go through numerous shenanigans to try and become the perfect butlers. It's pretty funny and there's bits of fan service here and there!
