I want a heroine that is like Nana from Koisome Momiji. I find those types of heroines to be the cutest, even though [spoiler] sadly she was not the main character's final pick T_T

What was she like again? Remind me. Name some qualities.

Her personality, in my opinion, is hard to describe. Bold, has those moments when the author makes her eyes big and blank to showcase her cuteness and boldness. Very passionate, I might add. Tell me if this is a good explanation lol, cause like I said her personality is hard for me to describe.

hmm, that's not much to go on. I can't remember which character she was. Is it like a Genki Girl (girl who is super energetic and happy and slightly airheaded)? Maybe these are similar:

Ashita Dorobou
Koharu no Hibi
Tasogare Otome x Amnesia
Dragons Rioting has a few chars like that
Doubt! (AMANO Sakuya) has one char, but not much screentime yet
Sora no Manimani

I'll see about those mangas ;o, but she is like... it would be better if you read a chapter, maybe the second chapter. Maybe you can tell how she's like after seeing one chapter because she leaves a bit of an impact, in my opinion.
