TBH, I actually liked Marquis as a 2nd ml, but he was too righteous, which made me lose my hopes for him.

Yeah... The one who loved fake Yvonne the most was the marquis, then one who killed and the selfishly reversed Penelope's time unendingly was also him. Causing the original Penelope's repeated death (she had a complete soul back then) but the soul completely shattered unable to reincarnate as whole anymore. Only a tiny piece of it managed to reincarnate that is current Penelope from the modern world.

While I do like marquis, but just imagining Original Penelope's repeated death is just sad, Marquis was the one who did that without consideration for Penelope's will. Being brought back to life and repeatedly killed only to save the people who killed her/hurt her/neglected her is just tragic.
