I don't have a DOUBT in my mind that Nick is attracted to Kyle. Just look at Nick's eyes when he's talking to Kyle. It speaks for itself.
Yep! Exactly that. In the Wolf Gang Puck video, when he first showed up, Nick's eyes just lit up, and it wasn't because he was talking into the camera.
Plus, he dressed up. If JoJo had any ability to read human emotion (or if they'd been with a decent human being instead), he'd have pulled Kyle aside and said "He is on a date with you right now."
Nick, I know you're not reading this but two things:
A) I promise, Jesus loves you just the way you are.
B) You can do so much better.
Kyle, I know you probably are reading, so two more:
A) If you are something other than straight, being honest about something for the first time in your vlogging career would help you both as a person and a creator
B) He deserves better than you. Treasure it.
