Gender matters apparently.
Hiromi Miyazaki is first born in her family's business. One problem. She's female.
Just because she's a woman her family looks down upon her and thinks she should have never been born. She has hidden her feelings with a massive lock so big she doesn't even know her own feelings.
The only thing she wants is to be loved by someone. But she's forgotten how to love herself and her friends. Her heart is now empty, that is, until she meets the host club.
