I Think I've Loved Him Ever Since Then

Story :  Mao Sugaya is a hot up-and-coming actor whose latest TV show is all the rave. His manager negotiates with the one-of-a-kind genius artist Eishi Kaida for him to do the theme song. Mao is through the roof when he finds out since he's a huge fan of Eishi's. However, Eishi agrees to work with Mao on one condition: that they spend an entire day together, and if he gets no inspiration for the song, the negotiation is off. Eishi avoids appearing in the media and hardly shows his face publicly, so Mao has no idea what Eishi looks like exactly. Once Mao meets Eishi, feelings of fear for someone from his past come rushing back to him. Although Mao is uneasy around Eishi, he proposes they spend the day pretending to be on a date...! What will Eishi say...?

This is the beginning of Mao and Eishi's love story!
