"Music brings people together", such was what Selene Clef's late dad engraved in her heart. That's why she practices non-stop to make her mom proud or at least snatch a bit of her attention. She dedicates all her time to music and has no time for other things - or so she thought. When a stray cat wandered into her room one night, she decided to adopt and name it Nathan, only to find out later that an aloof exchange student from the most prestigious music school is named the same - Nathan Lee. Does music really bring people together? Selene Clef does not really know - but she's about to find out.
