She liked Kei but felt she couldnt spend time with them as much as Eito could because they were both boys so "wished you were a girl" was more for a better chance as being "allowed" to spend more time with Kei. Its sort of two things going on at once.
Just like with Eito it's just that Noel likes Kei no matter what.
Next chapter wait is a killer, I'm dying to know if Kei-chan is gonna misunderstand her confession and lead into another misunderstanding arc, or if we're headed towards a more cards on the table love triangle. I'm expecting the former, but really hoping for the latter.
Damn, that atmosphere almost went rapey there for a second.
Thank goodness Kei just happened to be at the right time and the right place to repel the would-be rapist.
