Ji Rong has a weird kind of integrity.He's clearly not joining our team but he does have to choose between Chu Song, who took him under her wing and has been looking out for him, and Sun Liling, who has used him as a weapon against her enemies and bossed him around (and is better looking).
Chu Song might be willing to admit her dudes needed Sun Liling's protection or that odds are Sun Liling isn't gonna swing a revolution. Ji Rong would see both as admitting defeat, he'll never do that. If anything I expect him to get a lot more vicious than he was given Cai's 'provocation'.
