"Cousin, wuu wuu, I didn't do it on purpose, I was coerced by them. They forced me into this, please forgive me this time, after all, cousin-in-law was not really harmed." Jiang Chunlan cried pitifully as she begged Han Yu, hoping to soften his heart and let her off, but clearly she overestimated her own importance and underestimated Su Wenyue's place in Han Yu's heart.
Prior to this, Han Yu had no evidence, so he couldn't do anything to Jiang Chunlan. Otherwise, his birth mother would surely have intervened. Now that he had caught Jiang Chunlan red-handed, there was no way he would let her go, especially when Jiang Chunlan was still so lacking in tact, weeping and making excuses to evade responsibility, pestering him awkwardly. Her last sentence especially enraged Han Yu.
