Phoebus Chan here performing Minami Piece of Sena. Kimura Takuya played the piano piece in his competition in the drama Long Vacation. "Kimura" was a avid pianist who wanted to do well, but a girl interrupted his life one day and he finds it harder and harder to play with more affection because he had too much relationships in his life after that. But he won the competition with this piece because he played with his heart to show how much he cared about Minami.
*Phoebus said in Cantonese, "I played it until it spoilt :) :)" after he rehit the missed note.
