The emotions that Seo Dong-ju emphasized the most when announcing this breakup to the public were ‘emptiness’ and ‘regret.’ Since co-founding the skincare brand Kiana in 2024, she has poured all of her energy into growing the brand, from product development to overall operations. In particular, according to what she revealed, it can be seen that she has shown a dedicated attitude by working without pay to stabilize the initial business and improve the quality of the product. For her, who did not spare practical efforts to build the identity of the brand rather than simply participating as a face or marketing tool, this breakup must have brought a sense of loss that went beyond simply giving up her title.

The core of this conflict ultimately boils down to ‘differences in management philosophy.’ At a time when a new opportunity was being identified for the brand to take a leap forward, there appears to have been sharp differences of opinion among the co-founders regarding the direction of operations. In business, synergy occurs when partners look at the same thing, but if the ways of envisioning the future or priorities are different, this can quickly become the ignition of fatal internal conflict. Seo Dong-joo tried to find an agreement through much conversation and deliberation, but ultimately, they found a gap that could not be bridged and decided to go their separate ways. This may have been the most realistic and ruthless moment of management judgment that Seo Dong-ju had to experience as a businessman.

It is easy for the public to dismiss a celebrity's business as a flashy side job, but what Seo Dong-ju showed was in the realm of a much more serious business. She devoted herself to her work, losing sleep, with a sense of mission to go beyond simply exploiting her fame and deliver actually good products to consumers. As a result, she failed to coordinate management rights and had to withdraw from brand management, but the passion she showed so far served as an opportunity for many people to think again about the ‘other side of business.’ This incident clearly shows how easily a business can be shaken when the partnership system is creaky, no matter how talented and passionate the individual is.

The comments Seo Dong-ju left through SNS did not simply contain emotional appeals. She showed a mature attitude of cherishing the valuable connections and lessons learned through the brand, and defined her decision as a ‘stepping stone to growth’ rather than a ‘failure.’ Although her journey with the brand has come to an end, she has not broken her will for the future, promising to return even stronger. It seems clear that Seo Dong-ju, who has multiple identities as a lawyer, broadcaster, and businessman, will have gained an opportunity to grow further as a manager through this ordeal.
