Kim Se-jeong of the group Gugudan will be the ninth runner of the TVN monthly drama Record of Youth' OST. Sejeong's Record of Youth' 9th OST, 'My Heart is like that' will be released on each music site at 6 pm on the 13th. "My Heart Is Like That" is a song that contains the love story of Sa Hye-joon (Park Bo-gum) and An Jeong-ha (Park So-dam) deepening and deepening each other's grudges, troubles and deep longing. Sejeong's sad voice, singing skills beyond high and caustic, and the understated melody of the felt piano starting from the int leave a deep impression. Especially, it appeared for the first time in the 11th ending scene broadcast on the 12th, capturing the ears of viewers. After the second section, the chord and melody of the felt piano accumulate and deliver a dramatic reversal. This song reaches the peak of the song with a clear sound, leaving a deep impression on viewers and listeners.
