 If you liked
Hana to Hoshi

 ...then you might like
Ohimesama no Himitsu

There is not really much similarity between the two works, I just think if you liked one, you might like the other.
This is just a recommendation for you who likes shoujo-ai manga and doesn't know what to read next.
• Both are short yuri manga (about 5-15 chapters).
