Iwahada no Hanayome wa Ai de Tokasareru

Born with the power of Iwanaga‑hime (rock‑enduring princess), Iwao Iwako appears as a grotesque, stone‑covered “monster” — in stark contrast to her twin sister Sakiko, who received the beauty goddess’s blessing and is famed as the most beautiful woman in the imperial capital. Despite a lifetime of being ostracized and mocked, Iwako quietly harbors love for her childhood admirer — the gemstone merchant Saionji. However, Saionji ends up choosing her sister Sakiko in marriage, leaving Iwako heartbroken. Soon after, Iwako finds herself betrothed to Byakuran Kokumine — a cold‑hearted man reputed to be “cursed by the gods.” What begins as a seemingly bleak twist of fate becomes a compassionate and transformative romance, where love begins to melt away Iwako’s stone‑like exterior…
