Why should I ever thank you for taking my first kiss?!?

[Mikoto knew that Yato was stupid. But his mind was being blown by just how stupid he truly was?! Not only is he completely not understanding the math. He's wondering why on earth would he thank him later?!.

There was no way he would ever thank him for this!]

How would you feel if I walked up to you and suddenly pulled you into a kiss?
