I Thought I Was the Main Character내가 주인공인 줄 알았다; Naega Juingongin Jul Aratda; Я думала, что я — главная героиня; 私が主人公（ヒロイン）だと思ってたのに

Transmigrated into a romance-fantasy novel, the narrator wakes up as a nameless extra and convinces herself she must be the heroine. Enjoying the main-character route, she grows close to the supposed male lead, the second lead, and even the hidden villain... Until blunt questions get blunt answers: none of them actually likes her. Facing reality at last, she drops her beliefs, decides to find a husband who suits her status, and walks away before shes deluded again.
