Regrets Of A Second Male Lead

Chloe found a letter from her husband’s first love in her study.
[I wish your partner was Chloe.
If you would stay by Chloe’s side, I would be so relieved.
P.s. Did you notice that the child likes you too?]
Chloe, who spent happy days with her sweet husband and lovely son.
The day she found her old letter from her husband’s first love, Leila, in the library.
Her happiness is shattered.
It turns out that Leyla had persuaded her husband, Gerard, to marry Chloe.
Chloe, who deeply loves her husband, is desperate for her truth, which she has learned after 8 years.
In the end, to find out the full story of her case, she heads to the north where Leila lives…
“Madam, I was wrong. I was really wrong…”
The late Marquis Gerard Blanchett prayed to his wife on his knees.
The experience of being driven to the very end of grief had already left him out of his mind.
He doesn’t know what he’s talking about, he just clings to his wife and asks for forgiveness.
“So… Don’t throw it away, okay? Chloe, please…”
This man cries and cries.
What the hell is his truth?
