Osa 

The most caring and handsome person in the world. He makes you laugh like crazy and radiates sunshine and positivity. Osa will always be there for you when you need him and will never judge you no matter what. He’s shy at first but once you get to know him you’ll learn just how amazing (and freaky) he is. Hands down one of the best people you could ever have in your life.

He’s amazing, he must be named osa
