Do you mean Ai instead of Rihoko?

I hope you still like Tsukasa after seeing all of her arc.  Yeah, that's true. The ecchi stuff is in the second episode.

I heard someone say a long time ago that Japan is the opposite of the U.S.. In the U.S. you goof off in High School and get serious in your studies in college. In Japan you are serious in High School and goof off once you get accepted into a college.
