Look I'm really grateful someone picked that series up but there's really a little too many meme translations.
No troll or hate, just a little critism.

Not sure you can fall in love with someone you have never seen or even interact with. At this point he has not the faintest clue of who the Cinderella is. And as far as the pantie is concerned, he's basically just trading a pervert with another pervert. Why bother risking getting a worst pervert rather than go for the obvious Wholesome hot looking big titties kind smart and submissive Sayuki mother fucking senpai.
If you mean "seen or even interact with" as meaning meeting the person, then I'll point to you the existence of many fans of idols out there.
If it's just seeing, then you have people who fall in love with someone they're chatting with without ever seeing their face (and getting disappointed after flying halfway across the world to meet them).
It's probably not farfetched for Cake-kun to have... fallen in love with "Cinderella".
