which marmalade boy episode is it when miki locked herself in her room?

Answer 1

I think your talking about episode 8.

It is where Yuu's and Miki's parents trick her by saying that things are not working out between them and they are going to part and never see each other again. Miki gets mad and locks herself up in her room and cries and then Yuu crawls to her window to get in to talk to her.

I hope that's the one you are talking about.
