Entered politics with a desire for government change after Lee Jae-myung's presidential defeat
He stated that a strong desire for a new president and a keen awareness of the need for social reform were the direct motivations for his entry into politics. He had connections with aides to then-Mayor Lee Jae-myung during his time as Seongnam Mayor and felt a strong urge for reform after the presidential election defeat.
He said that he decided to run for National Assembly to directly lead reforms from within politics, having previously advocated for them from outside the political sphere.
