The Infertile Merfolk King's Pregnant Tidebound

Hotel maid Evelyn spent one night with childless Merman King Lucian, only for her stepsister to take credit for it. Needing surgery funds for her aging caretaker, she is branded a gold‑digger by Lucian and becomes his secret lover. After conceiving the mer realm’s long‑awaited thousand‑year heir, the two kings discover she is the real Tidebound — Seraphina, the goddess whose ancient curse ignited their millennium‑long feud.
