well I used excite translator to see what it says in chinese... It's a bit confusing (well it's a online translator anywayz), but I guess ayu's declaration (about continuing singing even with one ear's not working) kinda affect mika's message. Mika talked about the time when she first met ayu was around the time she wanna resigned (from being president of her company?). Ayu's attitude towards work greatly changed her mind.. And then she kept on talking...
Something like that...

.. LOL
One sentence attracts my eyes is she said something like, "With this person to live in a row, It is necessary to work in the same (according to the excite english translation)". I guess it means to match up ayu, she has to work very hard as well (cuz ayu is really hard working blah blah blah)...
