I could understand the reason why Shen Yi's parent forced her to marry ML. In the past, Shen Yi's parent was forced to have a marriage agreement with a midwife that delivered Shen Yi because of some difficulties. When Shen Yi turned 22 and was still unmarried, she had to marry the midwife's son. However, the midwife's son was a good for nothing so Shen Yi's parent married her to ML hastily.

But wasn't it enough to just marry? Why must force to her to consummate the marriage with ML? She was already mentally unstable before marriage and her parent's action only made it a lot of worse for her. And what made it even worse, she was also forced to give birth to her rapis*'s son (although ML wasn't also in a sober state at that time, it's still rap* for Shen Yi).

When she got a severe depression, everyone around her still blamed her for not knowing what's good for her. It's good that she finally got a new life in the new world after her su*cide but the one who got her suffered, her own family, didn't get any retribution. They didn't even realized that their real daughter was already dead and enjoyed the filial piety from the sensible MC. They regretted it indeed, but what's the use of it when the harm was done? The org Shen Yi was already gone and they couldn't make it up for her no matter what.
