Is it too late for my love

Athena, 17, fell in love with Uno, who was three years older. When Uno discovered her feelings, he rejected her, causing Athena to distance herself. Later, Uno learned that Athena had been in an accident, resulting in completely memory loss. Years later, Uno, now a professor, realized his feelings for Athena had blossomed, but it was too late. Fate brought them together again when Athena, the girl he once rejected, became his student. Uno's mind swirled with questions and what-ifs, leaving him uncertain about what the future held.
