well..
my manga would be about a teenage girl named Himitsu Utada who was blamed and shunned by her family for supposedly killing her own mother. she was abandoned for death when she was about ten. now, five years later her older sister, Akura, comes and invites her to live with her in Osaka, Japan. there Himitsu discovers her little brother, Monako, new friends, and love. so basically it's about a girl slowly opening up to a world where she can trust others and herself. she almost must prepare herself to be welcomed back to the family name from the rest of the family. but trust is so hard to build and so fragile, so easy to break.
more details later, i guess...
