No feelings for love? The stubborn prince is jealous again!

[Arranged marriage to love + sweet romance + both are virgins] Schemed against by her stepsister, her fiancé breaks off the engagement, and Qi Shu is caught in rumors that no one in the capital will marry her.
On that very day, the powerful regent came to propose marriage.
He said, "I have no feelings for love, and your non-jealous nature suits me perfectly."
Qi Shu agreed on the spot.
Even though he was twelve years older than her, rumors circulated in the capital that he had a hidden illness and was impotent.
It doesn't matter who you marry, she wants stability, he wants peace of mind, they each get what they need, and everyone's happy.
After marriage, she remained dutiful, neither causing trouble nor seeking love, nor expecting children, and even generously arranged for him to take a concubine.
But his cold, dark eyes grew increasingly intense.
Later, his body grew hot, and he whispered hoarsely as he whispered in her ear, "Will you have a child for me?"
She felt sore in her back and weak in her legs, only then realizing that the rumors were misleading; his health... was clearly fine!
The regent was a man of his word; he promised to protect her for life and never let her suffer any injustice, except in matters of love, where he broke his promise.
He couldn't wait for her to be jealous of him, so they could enjoy each other's company every night.
