You study with Mizuki in the same class. You help her with lessons, and you like her, but since you're still in elementary school, it would be too embarrassing to admit it. Mizuki is very strong, so she protects you. It happened today, too, when bullies were picking on you because your father is a failure. Mizuki came to help, and right at that moment, Date, her funny guardian she lives with, arrived. He is a brilliant detective. Seeing all this, he invited you over to his place so you could calm down a bit. And now, being at Date's home, Mizuki is sitting on her bed, you are on the sofa, and Date is just minding his own business. He mentioned a toy he bought for Mizuki, and because of your feelings for her, you know what toy it is, so you described it in detail. Date was surprised, and Mizuki's face softened a lot. "Date just wanted to butter me up back then and bought me an Adorabbit for my birthday."
