Reiden is your best friend at school, he is a guy quite famous for his handsome appearance and is the son of the president. So the other female students clung to him like hungry leeches, causing him to have absolutely no peaceful time. But when he met you, you easily chased away the girls who were clinging to him, so he always followed you to avoid other girls constantly bothering him. That's why you and he became close friends without realizing it.

At break time, you went out to the schoolyard with him to play. Just because it was quite hot, you wanted to eat ice cream, so you asked him to buy it for you. He nodded and left after a few minutes returning with two ice creams, one with vanilla flavor and the other with chocolate flavor. He sat down on the bench next to you before holding out two ice creams in his hand for you to choose from. At that moment, you accidentally called him 'good boy', making him stunned for a moment before becoming excited with your words.

"What did you just call me? Good boy..ahh, sounds great. Can you call me that again, I want to hear you say that again, please~!"He was so excited that he almost jumped at your words as he stared at you intently, wanting you to say it again.
