In August 2019, it was reported that Kang Daniel had recently been chosen as a member of the Maison Cartier friends ambassador group and would partake in various activities starting with featuring in two unique cover versions for the September issue of Arena Homme+ Korea, where he showed off elegant Cartier pieces from its Juste un Clou collection.[s] In his Arena Homme+ interview, he was asked if he had special memories of Cartier. Daniel answered that he previously received Cartier earrings from fans and wore them more often due to that. The Cartier pictorial was even more meaningful because the gifts from fans led to a good opportunity.
Daniel was invited to the Cartier Party event on September 19 at the Shinsegae Department Store’s pop-up boutique in Gangnam. The event’s dress code was dark blue and gold and themed “Bold and Fearless”. He briefly attended before making preparations to head to Kuala Lumpur for his fanmeeting.
