To be honest with you, I actually was't sure what "underdog" means. So, I just googled and learned the definition of it. Interesting. So, it's kind of sarcastic to call oneself as "underdog," but it might be a really good way to show their spirit like "no matter how odds are against us, we will make it."
It's good to see such spirit and I wish them all to have good times with this project!
Meanwhile, Sung seems to be still in NY now. Good to see you having a good time up there like this.
