The story-telling is a bit off?
First they are super close, with him basically helping her become viral. Then she starts making it big, ditches him, and disappears.
Next, when she's back, she doesn't acknowledge their history for 2 months, despite having that weird mission, which he actually might be helpful with. (Actually, that whole thing comes across as weird, too.)
And when he recognizes her, she shamelessly starts using him again.
At the same time as she's super shy ...
I don't know... It rubs me wrong...
