Mark, Tyler, and Ethan. The Three Musketeers of YouTube. Though moving to LA has brought the three fortune, fame, friends, and fun, they all left behind something so important in life: family. The one great thing Tyler left behind was his best friend, his little sister, Dannica, or Dani, as everyone calls her. Tyler loves Dani a lot for a reason. She's not like other girls. Hanging out with her is like hanging out with the guys. She doesn't worry about how she looks, she doesn't wear makeup or mini skirts, she makes stupid dick jokes out of the blue, she is anything but graceful and ladylike. In Tyler's eyes, she's actually fun to hang out with. Therefore, breaking apart was hard for the both of them. Luckily, Tyler finds the money for her to come out and visit. Just as Tyler told them, the guys really like her. But maybe one of them likes her just a little too much...
