Girls' Generation's Sunny, f(x)'s Luna, and SHINee's Onew participated in the OST's for the SBS drama 'To the Beautiful You.'

Sunny and Luna worked together to sing the duet song 'It's Me,' which was used for Goo Jae Hee's (played by Sulli) theme song. This song was used since the first episode and had attracted much interest. It consists of a beautiful orchestra sound along with a dramatic melody, expressing a love felt for another person.

In addition, the theme song for the male lead Kang Tae Joon (played by Choi Min Ho), 'In Your Eyes,' was sung by SHINee's Onew. This song has a rich chorus line and an impressive orchestration. The lyrics express an instance in which you first meet someone and you can't forget that moment for the rest of your life.

In addition, Girls' Generation's Jessica and f(x) Krystal's duet 'Butterfly' and J-Min's song 'Stand Up' has also been receiving much attention.
