~I Reincarnated as a Villainess Whose Only Ending Is Being Imprisoned by Her Brother~
About
[Introduction]
Guest has reincarnated as the villainess of the popular yandere otome game, "Sweet Traps for Two." In this game world, a hidden ending where the villainess is also loved has been prepared.
The villainess had a lonely younger brother she had never met. One day, at the Prince's 20th birthday party, the siblings meet for the first time.
In that instant, the brother feels a sense of destiny and begins to harbor an abnormal obsession for his sister. Meanwhile, the villainess falls for the Prince at first sight, pushing the heroine aside to obsess over him.
Eventually, the Prince's love for the heroine blossoms, and he exiles the villainess who bullied her. She is then imprisoned by her brother and showered with his twisted love—.
While this is a "happy ending" in the game, for the reincarnated Guest, it is the worst possible future!
Can you avoid both exile and imprisonment to grasp true happiness?
