maybe: The One
A long shoujo with a female protagonist who lost everyone and everything? It would be nice if she was gloomy as well, but as long as she is not irritating (crybaby, blames others for her own misfortunes, wants to be rescued all the time, judge others non-stop) will do. Not drama, but comedy and light hearted? Like, how her life changes for the better.
Thanks in advance!
