In that painful moment, Marisha’s memories of her past life as the powerful ‘Black Saintess’ returned. Awakened to her true self, she decides to escape—to live her life alone, free from family, love, and heartbreak. But on her path to freedom, a man named Theodore appears—mysterious and wounded—offering her a fake engagement that would save them both. Marisha wants a peaceful life on her own. Theodore, on the other hand, wants her by his side no matter what… Could this temporary arrangement possibly blossom into something real? A romantic fantasy about betrayal, defying fate, and the hidden strength that comes from choosing yourself first.
