Reborn as the Man Who Takes Away the Protagonist’s Beloved Childhood Friend

Rader says:

Add Yandere tag to this. So called Childhood friend, main heroine who got stolen in the end was the man villain after all. She loved the other child hood friend to death and hated the Game Beta Protagonist and his entire family to death. She is crazy enough to have photos on wall with Beta Protagonist face obscured with markers or so. She hated him so much that she is willing to do anything to destroy him completely. It will not be wrong to say that even without reading anything further she is the one who messed up women around him and then acted as if he cares about her and when he had no one left besides her gave him ultimate knockout punch.
