Beautiful... But i do feel like the main story needs more explanation

From what I understood, what ended up happening in the 1st timeline was in large part due to Grey's sabotage, not of El, bc he didn't know it was his 1st love, but of the Duke, whose father ruined the redhead family after the lady refused him. He got the duke to take his most trusted aide as a concubine, which ended up driving El to despair, but also was probably intended to ruin the duke idk how bc El never learned and timeline2!Grey never got that far.
