Read manga I Will Not be Overshadowed by my Twin Sister in This Life / I Won’t Live In The Shadow Of My Twin Sister / 쌍둥이 왕녀로 살아남기 / 今世では、双子の姉の影としては生きません
Right before I died, I discovered the terrible truth, my seemingly perfect twin sister had been deceiving me my whole life. The shock nearly drove me to wish for oblivion, until I woke up back in my childhood. I have to pretend to be a single princess together with my sister so no one discovers we’re twins! Given a second chance, I refuse to repeat the same life of abuse. I will reclaim the family bonds I longed for, the friendships I missed, and the healing power I never knew I had. Everything that was taken from me will be mine. Then I meet Yan, a talking bird with a warning. “The kingdom will fall unless you protect it.” Can I really survive this?
