The Yan family and the Song family have a commercial marriage.

She has a feminine beauty, fair skin, bright red lips, and always has a seductive fragrance on her body. She has been educated by the heirs since she was a child.
But when two people try marriage together.
It was only then that Song Nianying realized that her wife was so cute.
She would actually blush because of a small approach of hers, and would often stare at her slender neck in a daze.
When she teased her again and again, Yan Chuyu would say coldly and arrogantly, “Don’t get too close.”
Song Nianying smiled and continued to approach, Yan Chuyu stared at her with eyes like ink: “This is the first time I have warned you.”
…
When she received the 320th warning, Song Nianying was ready to move, and decided to overturn the warning and take her down.
But that day.
Thunder and lightning flashed in the sky.
Yan Chuyu sat at the highest point of Xuanming Pagoda, her eyes were bright red.
Beside her, a maid with a pale face and blue eyes lowered her head and asked, “Wang, what is it about the house that makes you so afraid to go back?”
She has been with the king for so long, and she has never seen her so anxious and terrified. Could it be that she is a wolf clan?
Yan Chuyu raised his left hand and caught a bolt of lightning, forming an electric ball, and slowly replied: “My wife.”

- Description from novelbuddy

High-school student Koremitsu Akagi finds himself attending the funeral of Hikaru Mikado, who had died in an accident during Golden Week. He’s not sure why he’s there, as he only exchanged a few words with Hikaru at school. However, Hikaru doesn’t seem to be completely gone from the world, as he comes back as a ghost in order to fulfill a promise to Aoi Saotome, his fiancée. Since Koremitsu is the only one who can see him, he asks him to carry out his promise in his place.

Complying with his request, Koremitsu tries to fulfill Hikaru’s promises to the rest of his “girlfriends”, helping them overcome past misunderstandings and repair broken relationships.
