Reborn Girl Swears Not To Be His Lover

When she was reborn to be her nineteen again, Ri Chu swore that she would never repeat the same mistake again. 
She wanted to study well, study the classical Chinese medicine seriously, and refuse to waste her precious spare time on part-time jobs. 
She wanted to apply for a grant and refused to let her brother's treatment be interrupted because of her pride. 
The most important thing to do was not to meet Jun Yu, not to be taken seriously by him, not to be his lover.
