Yandere is, to put it bluntly, the king of idiots. Most people are completely unable to control the love of a yandere. When two yanderes meet, they hit it off immediately, and they hate meeting each other so late. There are sparks and lightning all the way.
You are the most perfect work of art in the world. If I can't get it, I might as well destroy it.
You are the most delicious food in the world. It is too luxurious to eat it in one bite. You have to savor it slowly.
If you leave I will destroy you.
If you betray me, I will eat you.
Dear don't give up on treatment.
Baby, I'm just giving you the bed.
