Alain couldn't believe what he was hearing about Mairin's reasons for forgiving him, until he saw why he deserved to only be forgiven because of Professor Sycamore and his staff. Then, Alain noticed what Mairin was wearing. He blushed up a mess of red at the sight of Mairin's swimsuit, so he covered his face with his hands as a result.
Alain: Um, Mairin, what's that you have on, right now?
Mairin knew what Alain was talking about and suddenly it dawned on her that he might have had some of his own weaknesses and limitations.
Mairin: It's just a one-piece. It's not like I'm showing that much skin. Grow up, Alain.
Alain: At least, put on a cover-up or something to make yourself more decent.
Mairin: Quit being a child, Alain. I'm gonna go in the water. And you, you should really learn how to talk to girls.
