Gan Lin was Tian Rujing's senior disciple, and had long served as Liu Ziyue's guard. Although Liu Ziyue was brutal in nature, he treated Gan Lin quite generously. Gan Lin should have followed Tian Rujing's instructions to remain uninvolved in the matter, but ultimately, he couldn't let go of the years of kindness and secretly stepped in to save Liu Ziyue. He allowed Shou Jizhi to decapitate a young eunuch nearby, and smeared the blood on him to feign Liu Ziyue's death.
Afterwards, Gan Lin escorted Liu Ziyue out of the palace and let him leave on his own, thus saving his life.
Only after losing the throne and leaving Jiankang did Liu Ziyue recall Chu Yu's hesitant words during their last meeting. It seemed clear she knew of the rebellion, but she kept silent. Knowing his reinstatement was hopeless, the person he resented the most was Chu Yu.
