Fleeing Famine: I Can't Handle Life with My Clingy Merman Husband

[Only devoted to each other + one-on-one romance + pocket dimension + farming + System + fleeing famine + sweet, satisfying romance] Yu Shi's secret crush, the interstellar general Shen Yuhuai, was dead! Yu Shi went to find her beloved's remains, but unexpectedly transmigrated with Shen Yuhuai to ancient Earth, in the midst of a chaotic era of famine and flight. People fought over food and robbed and murdered one another everywhere. Shen Yuhuai, once cold as ice, had also lost his memory and turned into a clingy mermaid. At the slightest disagreement, he would use the beautiful fish tail beneath his clothes to curl around her ankle. Yu Shi: How could anyone resist that? Of course she had to take care of her own secret crush. No food? Then she'll grow some! Anyone with ill intentions gets taught a lesson! Yu Shi led a massive group of refugees in building a Peach Blossom Haven, and their lives grew better by the day. Now it was time to find a way back to the interstellar age. The “gentle and considerate” mermaid boy wrapped his tail around Yu Shi and pulled her into bed, drawing close with a pitiful look. “Why are you leaving, Sister? Don't you love me anymore?”
