Since a few years before, I began drawing a manga called "Sweet Life". Here's the main story:
Miu Nao is a normal high school girl... with not a really normal life in fact. Her parents fled away abroad, leaving her with an uncle in huge debt due to his fragile health and who doesn't know how to live by his own self. Moreover, before leaving, her parents chose her future high school, which means she have to attend it while living with her incompetent uncle. And finally, because his uncle doesn't gain enough money to support Miu and himself, she have to keep her age secret in order to work in a Japanese restaurant.
Yes, life is hard for that
