However, the Sarim faction did not control any army nor had financial base. Sarim's power was solely dependent on the king's support, which Jo believed to be steadfast in their mutual pursuit of reforms. However, Jo's unbending character and his frequent remonstrations to Jungjong to support his radical programs began to irritate the king. Even when he disagreed with Jo, Jungjong almost always ended up adopting Jo's petition because Jo would refuse to bend his will and Three Offices would threaten to resign en masse. Furthermore, Jo and Hongmoongwan officials often instructed Jungjong on the ways of king in long lessons. Because Jungjong was not a crown prince, he had not received a thorough royal education expected of future king, and Sarim scholars sought to rectify this, believing that only learning could prevent a despot like Yeonsangun. Jungjong began to feel hounded by his subjects and resented it.
