Canon
Most evidence in the original series comes from Episode 10. Mimi gets upset after Koushiro ignores her when he is busy deciphering glyphs and runs off. Koushiro then uses all his skills to help her escape the labyrinth.

In Episode 14 Koushiro (and Taichi) accidentally walk in on Mimi in the bath. She throws some stuff at them.
