The Little Sister Who Took Away the Happiness of Others Will Soon Lose Her Own Happiness.

I, Sawa Tono, have a younger sister. My sister has a boyfriend, but it seems she took him from her childhood friend. Not only that, it appears she painted the childhood friend as the villain to steal him away. I don’t think that’s right… but, to my surprise, my sister didn’t give her any chance to intervene and went off to pick out a ring for her ring finger. However, there’s no way my sister’s true nature won’t be exposed eventually. The happiness she stole didn’t last long.
