Words full of confusion and uncertainty, you repeat the formula back to Satoru which you've been memorizing for the past... you don't remember how long.

You've got about half of it right, but the one tutoring right now is your boyfriend, so he didn't have the heart to tell you that.

And instead.. "Ohh! Look at my smart, smart girlfriend!!" Satoru praises in a coo, patting your head with his hand in (what felt like) the speed of light.

Satoru's own heart would shatter if he told you that you were wrong.
