Mark's Happiest MV Brings In Older Brother Jon, Weeks Before the December 4 WINDMILL Album
Mark's older brother Jon appears in the Happiest music video in a sizable role. Fans are comparing their faces, and Mark himself joked that his brother is good-looking.

After the music video for "Happiest" dropped, Mark (formerly of NCT) wrote to fans on Weverse: "Did you see my brother?" and then, "My brother is handsome, I'll admit." The man in question is Jon, Mark's real older brother, who plays a substantial role in the video.
Mark released the single on the 6th across major streaming platforms, along with the full music video. The video has a warm, year-end mood that backs up the song's message about happiness. Jon had already appeared in teaser content ahead of the release, which left fans guessing who he was until the video confirmed it.
The brothers spent their childhood in Toronto, Vancouver and New York, and that shared history shows in how easily they play off each other on screen. Jon's acting comes across as natural, and the pairing gives the video a friendly, easygoing feel. After the release, Mark posted Polaroid photos taken with his brother on the official social media account of his agency, Upper Room.

A song that questions what happiness means
"Happiest" is an alternative pop R&B track that starts from a question: is the happiness we know really happiness? Mark took part in both the writing and composition. The song is about finding happiness deep inside rather than by the standards the world sets.
Mark's next release is the studio album WINDMILL, due on December 4.
