Infinite F first performed as an unofficial unit at Infinite's 1st Inspirit Inauguration on August 17. The trio did a cover of Orange Caramel's "Bangkok City" which was well received by fans.

Infinite F was officially announced at the One Great Step Returns encore concert, held February 28 and March 1. They also performed the song "Heartthrob" for the first time. The song was eventually revealed to be the main OST for the KBS drama Hi! School-Love On, starring group member Sungyeol and Infinite fellow member Woohyun.

Akiko Higashimura, creator of Princess Jellyfish, provided illustrations for the album jacket. Koi no Sign debuted on the Oricon Weekly Chart at #6, selling 31,287 copies. The album was later released in Korean version titled Love Sign.

As part of Japanese promotions, a pop-up store was set up in Harajuku from November 17 to 30, selling various Infinite F goods and clothing items. In addition, the sub-group did a five-show showcase tour, performing in Osaka, Nagoya and Tokyo.
