Why Are You Sorry, Darling?

Synopsis

Secretly met her husband's mistress. She's pretty, delicate, and lovely, Seira. "I'll never break up with the Duke!" "That's exactly the attitude." "Huh?" A noble, well-off family, pretty, and a life that's not lacking in anything, I've been possessed by Tareia, so the only obstacle in my life is "You keep flirting with my husband." That bastard... no, I'll throw my husband away and live a glamorous single life! ...I was trying to live...? "I'm starting to wonder about you." "Leah... can I call you that?" "Madam, please don't divorce." Why are these men suddenly like this!
