If A Fey Asked Me "May I Have Your Name?" And I Give Them A Name Of An Already Existing Person Who Is

If a fey asked me "May I have your name?" and I give them a name of an already existing person who is not me, would said person's name belong to the fae?

Bc, the fae can't have my name unless I give it to them, like a form of consent. But the person who's name I gave them didn't consent to their name being given to the fae.

But if I asked the person "May I have your name?" and I'm a human, under fey terms I technically "own their name" so then would it be mine to give?

But if I never had asked and they just said their name, would the fae just not get the name bc it never was mine to give away?

Does anyone have any tips for keeping characters from being OOC when writing fanfic?

I struggle with keeping fictional characters' personalities consistent and wanted to know if there were any tips I could use to better my skills.

Am I the only one who does not understand where the concept of fanon pregame Shuichi?

I'm not hating on it or anything, I just don't understand how we got a "batshit insane Yandere Shuichi headcanon" from the brief maybe one-minute clip in the game.
