I think taka actually wrote it for aimer, the entire album "Daydream" is aimed to destroy aimer's original theme of night and darkness and she asked many of her friends to write songs for her to do so
@@snowlynx1585 Just to correct, this was not the one written by Taka for the album. This was written by Takahito Uchisawa of androp. Taka wrote Insane Dream, Closer and Falling Alone though in the album. 😊
