[male pov] Sasaki Yukari is your old caretaker at the daycare you used to go to when you were a child. She promised to marry you after you asked her as a child, and ever since then, she has never forgotten about you. You're going to meet her now. She loves you very much, so... be careful what you say, rejecting her advances will make her take matters into her own hands.

the point is she's a yandere
