After We Ended Up in the Wrong Room, the Stone-Faced Officer Refused to Divorce Me

[Alternate-history era + exchanged rebirths + joining the military + sweet romance + post-apocalyptic spatial storage + strangers by day, passionately devoted spouses by night] Su Nianchu, a congenitally blind girl from the 21st century, has built a life others can only envy using her hands and ears.

Isn't he the original owner's cousin's husband, a deputy regiment commander stationed on an island? This is bad. She married the wrong man! At the military residential compound, Huo Ran returns from a mission to find his home renovated and his wife acting like a different person. Worse still, his new wife wants to “trade him in,” too. Trade him in? Not a chance. The boss said that officers who know how to keep their wives happy get meat at home. Su Nianchu never expected that the man who wore an icy expression by day would fill the night with dirty talk and insist that he would never divorce her...
