Parents want you to be separated from the person you love the most. Even if your lover wants to commit suicide, will you separate from your lover for filial piety?
As the saying goes, loyalty and filial piety can't be satisfactory since ancient times. In order to be filial, you can perfunctory your parents, but you must never be separated from the person you love, otherwise the consequences will be serious and even fatal. I hope you can be emotional with your parents, and make them change their minds and take back their lives. That's all that matters.
