Garbage husband parading a man getting what he deserves while FL gets her chance in the spotlight is what we love to see.

I really like how both leads bring something to the table and that it's actually ML who comes up with the contract marriage idea. They're genuinely a good match and it doesn't feel awkward or forced. FL was put in such a terrible position in her first life and faced a horror no mother should have to experience, but she was also a trailblazer girlboss who ran an incredibly successful business despite her circumstances.

Honorary manga addition because it's one of the rare isekai series that isn't about a villainess who has an engagement cancelled. Yes it's reincarnation into the modern day rather than the past, but it's fascinating to see the past drama and events affect the present as they all try to unravel the mystery of how they died. The "past" is intricate and detailed and the mystery is suspenseful and rife with drama. I've been following since 2009.
