'Feel Special' sang the heart-rending moment presented by precious people as they walked through a dark tunnel of mind like a black night. It is all the more special in that it is a song inspired by the conversation JYP chief Park Jin-young had with TWICE members. The feelings TWICE experienced as they overcame difficult moments on their four-year journey after their debut became the starting point for the song. Park Jin-young wrote the song with the hope that when she suddenly wants to sit down in fear, someone's warm words will help her get back on her feet. TWICE also sang the song hoping that it would be a boost to everyone. The arrangement involved Lee Woo-min, who composed 'KNOCK KNOCK' and arranged 'What is Love?' with Park Jin-young. 'Feel Special' is another masterpiece produced by the combination of 'Park Jin-young X TWICE X Lee Woo-min'.

The music video of 'Feel Special' expresses the song's main message, 'Special Moment', with light and colorful objects, giving it another visual pleasure than ever. It is said to contain TWICE's unique dynamic energy and trendy charm. The bright smile that makes you feel special maximizes the message and lyrical atmosphere of the song.
