I have two questions about the anime Kaleido Star...?

The main character is Sora and throughout the series a boy named Ken Robbins was in love with her. I just watched the final episode and Ken doesn't reveal his feelings to Sora!!!! Is there a manga where it goes beyond the anime where Ken and Sora get together? My other question is I abslotely loved this anime and would like to find another one like it. Any suggestions? Thanks!!!!
