He's afraid of ghosts but ironically, he's friends with one

Takaki Yuya lives a life of a normal highschool boy until the day his parents got separated and he transferred in his father's hometown. Everything in his life changed from his home address to his new school where he finds it hard to cope up with everyone. From the lively and stupid Takaki Yuya he then become introvert and seems unapproachable that makes his classmates afraid of him. One day as he loiters around the campus he heard someone plays the old piano in the music room. The melody was inviting as if telling him to go inside, as he enters, he saw a beautiful ghost man playing the piano gracefully and again everything in his life changed.
