Slow to mature after marriage

A slow-witted and composed female forensic doctor ✖️ A cold, roguish, and sharp-tongued young master
[A sweet story of arranged marriage leading to love, love that grows over time, and a slow-burning romance]
Bo Yan agreed to marry Mu Siwan and proposed three principles for their marriage:
Let's not talk about feelings.
No interference.
Treat each other with respect.
Married for three years, her husband has always been abroad, and all Mu Siwan has received is five million yuan deposited into her account every month.
They lived a carefree life.
Later, when Bo Yan returned to China, Mu Siwan indeed listened to him and always kept the three principles in mind, never interfering in his private affairs.
But Bo Yan was acting increasingly strangely.
"Mu Siwan, husbands and wives should take care of each other."
"Mu Siwan, after you go on your business trip, please call me every day to let me know."
"Mu Siwan, your husband is just someone you can rely on."
"Mu Siwan, please... like me too."
Mu Siwan looked completely bewildered: "..."
What happened to the three principles for marriage?
-
Bo Yan's initial reason for marrying Mu Siwan was that she was helpless and therefore obedient.
He needed a docile and obedient wife for a marriage alliance.
Later, Bo Yan hoped that Mu Siwan would have someone to rely on, that she wouldn't have to be obedient, and that she would fall in love with him.
In this unfamiliar marriage, he was the first to fall into it, and he was also the one who ultimately couldn't be saved.
