Here are some Spoilers i have found (not from me I just copied it):
Trigger Warning though, there are very detailed description of
r*pe by Non Male Lead, r*pe by Male Lead, and su*cide in this story
Also this is by the same author as Omega Complex and Alpha Trauma, to give an idea of the author's writing style.
The basic plot:
Jung Seijin and Kwon Yido were in an arranged marriage where everything that could go wrong, did go wrong horribly. It ended up in a tragedy.
But that was their first life and the story started at the beginning of their marriage in their second life.
Not that Jung Seijin remember, but Kwon Yido certainly did and was doing his best to fix everything that went wrong with their first life (which he mostly caused by being a flaming piece of sh**).
