Billionaire Girl

Kei Takato, an ordinary university student searching for part-time work, receives an irresistible offer: to act as a mathematics tutor for his professor's niece, Yukari Fujioka, twice a week and for ten thousand yen per hour. Taken aback by this lucrative deal, Kei accepts.

However, despite her immense wealth, Yukari lacks friends and real-life experiences; it is up to Kei to save her from solitude, all while managing his own growing feelings.
