Prince + Princess 2
僕だけのプリンセス
The second princess refers to the second sibling among three sisters. Being stuck in the middle, she's not adored by her dad nor loved by her mom. This is a cause to her weird personality where she tends to feel inferior to others and yet puts up a very tough and strong personality in front of others. Things start to change when she falls in love with a wealthy man, Ning Huan Yu. He is a rich man who is often pranked because of his innocence and obliviousness towards things.
