Even though the Tang Family had never harmed him, they almost cost his wife her life, and emotionally and logically, he had to stand by the Song Family. Therefore, he couldn't help but pay attention to these matters.
As the heir of the Tang Family, Tang Yuan naturally became the focus of his attention. He never expected such an outstanding young man, due to familial entanglements, to resolutely give up everything. This was indeed commendable for its bravery.
Yet, to Han Dongchen, it seemed foolish. Admirable as it was for someone to act bravely out of emotion, he found such disregard for the consequences, and such a headstrong way of handling matters, unacceptable.
Now recalling how Tang Guoren had once acted the same way, he came to terms with it, a case of 'like father, like son'. Tang Guoren's lifelong frivolity, which he thought was true love, ended up causing devastating consequences for a mother and daughter and threw the family into chaos. Perhaps that was his karma.
