I guess that's one way to do it. Personally, I was thinking of hitting "sensei" with the classic, "A female teacher is trying to physically drag away a male student during a day off? Do I need to contact the schoolboard?" But, passing together works, too, I guess.
Thought I had by the end of the chapter, too: the rules state he can't be confessed to prior to graduation... but do they say anything about him confessing?
