Seeing Yun Qingyue's angry expression, Yun Feixue's face turned pale. He knew the question his sister asked was unanswerable. He certainly didn't have any "mental illness," but his sister wasn't wrong either. Liking his own sister was undoubtedly wrong!

With the trump card already played, how was he supposed to respond? Seeing Yun Feixue's pale face staring at her, unable to utter a word, Yun Qingyue didn't care what her brother was thinking. She directly asserted her authority as his elder sister and spoke calmly:

"Feixue, I don't care whether you admit you have a problem or not. You must agree to this marriage with the Zhang Clan's Young Lady! Your brother-in-law and I are doing this for your own good! If you dare refuse or try to escape the marriage, I will no longer acknowledge you as my brother!!"

It was the first time Yun Qingyue had spoken so harshly to Yun Feixue. Honestly, she felt a bit guilty, but Chen Lie was right. To cure her brother, sometimes she had to be firm. She couldn't continue indulging him as she had in the past. If she hadn't spoiled him so much, how would he have developed a mental disorder? Now that there was a treatment plan, she had to help him get better no matter what!
