I reincarnated as Luna, a supporting character who is accused of ruining the heroine and hero’s relationship, and is mu*dered. I’m not interested in someone else’s man, but the heroine’s friends bully me every day. “Why are you trying to get close to someone who’s already taken?” “That’s right, please stop! Why are you doing this?” “Stop doing such terrible things!” So Luna decides to announce it in front of everyone. “I don’t want someone like Fersen even if you beg me to take him so stop bothering me.
