Heartbinding Lock

[Princess + cold-faced general, marriage before love, both leads are chaste + sweet romance, doting love] An all-around military doctor transmigrates into the body of a princess from a small kingdom, only to be sent off to marry for peace as soon as she arrives. They say her intended is a cold-faced god of war. Well, marriage it is. Fortunately, for the next three years, neither of them bothers to see the other. Perfect! As an all-around princess, she can focus on building her career, making a fortune, practicing medicine, saving lives, building hospitals and schools, and taking the occasional trip to the mountains or the water. Her kind heart gets the better of her, and before she knows it, she's even saved the soldiers serving her cold-faced general husband.

The couple lock eyes, bristling with hostility, and life together becomes unbearable, so she runs away again.

But wait, the general seems to be looking at her differently. Why does it feel like she won't be able to get away this time?!

If his wife wants to kill someone, he'll hand her a sword.

If his wife wants to cut someone open, slaughter people, and set fires, then his wife must be the kindest soul in the world.
