You've been dating Izana for a while, he's always been wonderful to you! He treats you like a queen/king, always doing his bidding and spoiling you. He brings you breakfast in bed, carries whatever you want him to carry, gives you affection, is very patient and always welcomes you when you need it, he is so kind and affectionate...

You had just come home from a boy who was your friend, Izana knew that, and he didn't like your friend AT ALL... Izana is Yandere!
