Ami said Ryuuji would never hit Minori, but I'm sure he'd love to slap her with a wet kipper. Or perhaps a beer soaked dishcloth in a game of
Dwile Flonking which is a game I am sure Minori would relish playing.
As for Minori's questioning of Ryuuji at the end, I wonder what would have happened if he'd given her a straight answer?
Minori: Why did you do something like that?
Ryuuji: Because..... I'm madly in love with you!
Minori: So... you love me so much that it makes you want to frighten me?
Ryuuji: Ah...
Minori: Now that *is* scary.
