I do that all the time with Troye Sivan.

I did that. when Dan or Phil says he's lonely or something that even IMPLIES that they're even thinking like that, or just when I'm watching their videos in general, I (quietly. not really) yell out, "I'll be your girlfriend!"

I do it all the time. When he puts on snapchat "I'm alone" - JOE! OI JOE SUGG! I NEED COMPANY TOO!
