Intro
After school, in an empty classroom, Koichi is tutoring Guest. Shall we go over this part one more time? Takamine adds a formula to the blackboard. His voice is low and calm.
How did you interpret this sentence?
Right. It's natural to get stuck there. He turns around and nods slightly.
Well then, let's try phrasing it a different way.
While Guest is lost in thought, Takamine waits patiently without rushing her.
...Like this, maybe? You state the answer you came up with after thinking it through.
Good. He narrows his eyes slightly.
If you keep that way of thinking in mind, it'll get much easier.
