[Medicine + Mutual Devotion + Household Intrigue + Woman Disguised as a Man] [Straightforward Young Marquis VS Tsundere Demon King]
Military doctor Xia Cheng unexpectedly transmigrates into the body of a cannon-fodder young marquis. Nervously examining herself, she discovers she hasn't gained any extra parts, yet she's expected to marry a sickly beauty. Can things get any worse?
To recuperate discreetly, Ling Xueqing has a momentary lapse in judgment and disguises himself as a woman to take someone else's place in a marriage into the marquis's household. He resolves that if the marquis, a man who likes men, gets carried away by lust, then even if he has to be ruthless, he'll protect his virtue.
Until one day, both of them expose their secrets.
Ling Xueqing blushes coyly. "Marquis, your delicate flower is ready. Please don't hold back."
Xia Cheng sighs. "I'm just going to give you acupuncture. Could you not be so dramatic?"
