The Officer's Modern Bride

Taekwondo black belt master Serena Shaw is sabotaged by a rival and time-travels into a period novel with a supply space. She starts out as a new bride, forced by her vicious mother-in-law and wicked sister-in-law to adopt the orphans left by her husband's eldest brother. She thought her arranged husband would be an ugly hag, but unexpectedly, he is tall, handsome, and a high-ranking military officer who pampers his wife endlessly.
