Hello!

I'm looking for a certain 1 volume shoujo manga, but since it's been AGES since I read it (probably around 2008 😛 ) I don't remember much >.<

It had:

*cute shoujo art
*school life
*kinda dark plot (for a shoujo manga)
*something about butterflies or flowers (?)
*some type of competition between the students (or two boys)
*might have been a collection of short stories (not sure)

I do remember this one scene where the main character (long haired girl) was talking with his brother in the school grounds 😀

But that probably won't help one bit DX I'm sorry...
