If I Say, I Love You

"If I Say, I Love You" (Korean: 오늘만 I Love You; lit. 'Just for today I love you') is a song recorded by South Korean boy band BoyNextDoor. KOZ Entertainment released the song as the group's first digital single on January 6, 2025. Members Taesan and Woonhak wrote the song with co-writer Kako. Described as a dance-pop song, "If I Say, I Love You" revolves around the emotion of "patheticness", narrating the aftermath of a breakup in a self-deprecating fashion. The single was accompanied with a winter-themed music video with elements of a slice of life plot.

Commercially, "If I Say I Love You" became BoyNextDoor's first major hit in South Korea, their first ever song to enter the top ten of the Circle Digital Chart, and was the best performing song by a male group in 2025 on the chart. It received awards during its promotion in the music programs of South Korea. A Japanese version of the song was released as a digital single on January 31, 2025, through Universal Music Japan.
