 When Hatori told Akito that he intends to marry Kana, Akito took it upon herself to punish Hatori and injured one of his eyes, which induced a traumatic experience for Kana.To make matters worse, Akito berated Kana for Hatori's injuries, and guilt tripped her into believing that wanting to marry Hatori was a mistake she should have never made, since she is incapable of lifting the family curse.Overridden with guilt, Kana was unable to lead a normal life following the incident, which eventually led to Akito suggesting that Hatori should erase her memories.
