I can prove 3 things
1) Luca is Enna's oshi.
2) Enna lied about not watching Q playthroughs.
3) Enna lied about not getting backseated.

Backround:
Enna played Q Remastered and people were surprised at how quickly and easily she breezed through the levels. This is highly suspicious, because Enna is known to be dumb as a bag of rocks. At the end she strutted around like a peacock taking praise for how intelligent she supposedly is. But she is a liar.

A week ago, Enna came on Kyo's stream when he was struggling with a problem, she seems to know the answer:
"Draw a comma"

She sounds confident in her answer, like she's seen it before. Kyo asks "why a comma?" She says "it just seems right to me, I can't explain it"
>https://www.youtube.com/watch?v=ddrk7iRLrpc&t=11088
She also tells Kyo to "draw an L-shape"
>https://www.youtube.com/watch?v=ddrk7iRLrpc&t=10375
She is half-remembering these shapes and doesn't know exactly how they should be used. But where do these shapes come from? Answer: Luca's stream.
Luca draws comma shapes:

Luca draws an L

Enna is "half remembering" shapes from Luca's stream, but doesn't know how they should be used. This means she didn't "look up" Luca's stream in order to help Kyo, she is remembering something she saw vaguely.
Later she looks up the answer for Kyo, and what she describes is exactly what Luca drew:

It is especially damning because the "comma" she describes is "backwards" from a real comma, just like the one Luca drew.
Even Kyo thinks it was weird:

This proves that Enna watched Luca's stream. Furthermore, the solution she remembers is from a "different but similar" problem, so she remembered the answer, but not the problem number. She most likely watched Luca's stream all the way through. She probably watches ALL his streams, because.....HE IS HER OSHI!! This also proves she lied about not watching any Q streams before playing.
Look here, she says: "I only stopped by for this one problem because I plan to play this later"
>https://www.youtube.com/watch?v=ddrk7iRLrpc&t=10633
And in her own stream, she made no mention that she had already seen other Q streams and pretended it was her first experience "except that problem I helped Kyo with".

The later problems take her more trial-and-error, but in these instances it's clear she's being backseated by chat.
"I need help, HELP!
>https://www.youtube.com/watch?v=hqCMTW1kFZg&t=18578
"Why won't you help me" begging for backseating. Then she pauses for a long time reading suggestions from chat.
>https://www.youtube.com/watch?v=hqCMTW1kFZg&t=18722
Her ENTIRE chat is nothing but backseating this whole stream, unlike other people such as Shu, she didn't say "no backseating".

At the end, Enna says "lowkey it was me doing everything"
>https://www.youtube.com/watch?v=hqCMTW1kFZg&t=20705
One of her backseaters superchats her, she says "I don't know what happened, I just randomly drew a curve and it made sense to me"

Long story short, Enna lied to look smart. Enna is actually dumb as hell.
