Lin Ze has already explained the matter of breaking the engagement to Meng Zongqi, Meng Linhe, and Meng Wenci who were left earlier after 'Meng Ruyan' returned to his room. Meng Linhe told him again that the Meng family had already let go of this engagement. Meng Zongqi added that it was his father, Meng Zonghe – and Meng Ruyan's grandfather, who proposed this engagement. Now, Meng Zonghe is gone. Meng Ruyan and Lin Ze also didn't have any affection for each other (well, who would since they never even met despite being engaged?), so it was time to break the engagement.
Lin Yao looked at Lin Ze after he listened to Lin Ze telling him what happened when he visited the Meng family earlier. "Cousin..." he called as his gaze turned complicated while he looked at Lin Ze. "Based on your tone... do you want an engagement with Meng Ruyan again?" he asked as he looked at Lin Ze.
Lin Ze didn't answer, since the answer is obvious.
