[Crossover] The Lady Is Both Beautiful and Irresistible

You have a simple, unremarkable wish.

Your fiancé dies young, leaving you with a vast fortune, and you live a happy life as a wealthy widow.

To that end, you plan to marry Muzan and spend every day hoping the sickly man will kick the bucket soon.

You accept the family elder's proposal and go on a blind date with a healthy young man from the Ubuyashiki family right in front of him...

One day, you fish the corpse of your healthy young man out of the pond.

Meanwhile, the sickly man's gaze grows more and more unsettling...

Muzan has a beautiful fiancée. He watches her put horns on him with his own eyes, then personally strangles her to death...

Jealousy, like a dark tide, gnaws at the demon's heart.

The instant he becomes a demon, his feelings are frozen forever in that moment.

Eternal hatred and... eternal love...

After Muzan's death.

You take in a wandering sorcerer and successfully have a daughter with him.

Sadly, you die of illness one day. He goes completely mad and turns your daughter into a divine weapon in an attempt to bring you back to life.

You: "..."

In your next life, you live an ordinary life.

Until one day.

You take in a dad with a huge chest, washboard abs, and a Waku Waku vibe...

You: "..."

(The lady is his fiancée, not Muzan's wife; she's covered in arrows pointing at her.)
