Well it's true. But being a doctor why so much under confident is still a mystery ? What is the back story of Monami. Her father seems bitter towards her mom.
Or either she grow up without her mom and Dad being strict ...
People can be like that
She does talk to people and can interact
But she lacks that firmness or maybe she just doesnt know that she has that strong nature and hence is meek
Her father looks strict and that might make her fearful of him from childhood...and she never had someone to give her that motivational speech of being self-confident and calling a spade a spade
