SAY CHEESE!BOYNEXTDOOR

BOYNEXTDOOR, currently on a hot streak and produced by ZICO.

Created as the official anniversary song celebrating the 85th birthday of Tom and Jerry, this track features an appealing hybrid sound that fuses rock ’n’ roll and hip-hop.

The lyrics depict a “best buddies” relationship—always squabbling yet inseparable—capturing the very essence of the cartoon’s world.

Released as a digital single in November 2025, it also made waves when the members appeared with Tom and Jerry at an event in Yokohama and performed a cappella.

The chant that feels like a cue for taking photos is a lot of fun, making it perfect for parties with friends or any moment you want to smile.

It’s a song that gives you a boost of energy.

A friendship song by MONSTA X’s two rappers, Joohoney and I.M.

If you’re a K-pop fan, you’ll probably recognize the meaning of the title “Chingu-e” right away.

Chingu means “friend,” after all.

It carries the sense of “let’s be friends,” with a party vibe that says, forget the complicated stuff—let’s just have fun together.

The casual, everyday feel—like in Western music videos—also suits the mood of the song really well.

Billlie is a girl group that made their Japan debut in 2023.

Active across platforms like YouTube and Instagram, they sing “BYOB (bring your own best friend),” a song that carries a straightforward message to friends.

BYOB is widely known overseas as an initialism used on party invitations.

By replacing the last “B” with “best friend,” the song conveys the message, “Bring your best friend to the party.” It’s K-pop with an urban vibe, featuring airy, expanding synth tones.

Suho, who has led EXO as its leader for many years, released his fourth mini-album, “Who Are You,” in September 2025.

Rooted in alternative rock, the record captures a quiet moment of parting just before a breakup.

The band-driven sound woven by guitar and bass is layered with soft, fragile melodies, conveying the aching feeling of no longer being able to see what the other person truly thinks.

Both Korean and English versions are included, and the music video symbolically portrays a journey with friends wearing masks.

It’s a song that gently stays by your side when you want to quietly accept the end of a relationship.

An upbeat tune wrapped in a bright atmosphere and sense of speed.

SORAN, a band making waves in the Korean indie scene, released it in December 2023.

Though it’s a farewell song titled “Good Bye,” its warm send-off perfectly showcases SORAN’s charm.

Ko Yong-bae’s gentle vocals and the subtle sparkle in the sound make it feel like it brightens the listener’s future and gives you energy.

It’s recommended both as a graduation song and as a track to dedicate to a close friend.
