Oh, Sun in My Heart

[Both leads are romantically inexperienced / possessive pursuit / revenge / redemption / equally powerful leads] Xi means radiant light. She was the little princess of the Su family, born as the first rays of morning sun bathed their home. But later, all the light vanished from her life. Su Xi watched with her own eyes as her entire family was slaughtered. Her father's bloody handprint stained her princess dress, and her mother's warm blood splashed across her tender face. As the castle fell, its princess was swept into a life of hardship before she could even raise her sword to defend her kingdom. Picked up by Gu Meng, she fell into an even deeper hell. Three years of torment drove her to the brink of collapse. Then she met the first person to save her in her life, Sister Shi An. She protected and loved Su Xi, but... in the end, Sister Shi An died horribly in her arms. This time, the princess in exile still couldn't raise the legendary sword to slay the dragon. Su Xi began to erase herself. She was no longer Su Xi, but Shi An, living as her sister and seeking revenge in her sister's name... Given enough time, she would make every sinner grovel at her feet and bow in submission. She had factored everything into her plans: her dreams, her health, herself, even her own body. She never expected the gears of fate to begin turning. Ye Henian: Su Xi, please let your heart beat again, even after all hope has died! Su Xi, before you think about loving me, I think you should learn to love yourself. Don't let yesterday's downpour soak the person you are today. Miss Su, keep moving forward. Don't look back. You and I have a relationship of submission. I am the sword that submits to you. Use me. Step on my shoulders and flesh to climb to wherever you want to be. Reason could never prevail over a heart in love. She loved him, but he told her to leave.
