For a title with Yandere in it, I was expecting some yandere, but surprisingly, zero. Just another adorable vanilla Iorin story.

omg Thank you. Thank you very much.

I'm guessing they can't just go on full blast with every girl.
Also P's getting used to their...approaches so the situation doesn't get out of hand that much.
Doesn't change that he's being imprisoned here unless he signs the contract that has the 3rd condition written as a marriage vow. lol
It's not so much that there's no yandere but that it gets completely overpowered by the adorableness that is Iori.

There's a Chihaya chapter before this. No idea where though.
