Possession - Yandere!Akutagawa x Reader

People didn't call him human. He was a soulless executioner. What they did to him, and what he did later, resulted in just such an effect. His feelings began to wither slowly. The sense of guilt, any remorse, disappeared, and he seemed to reconcile himself to such a fate.

However, if that someone, that particular person who can change his perception, appears, how will he behave? Will he want to be part of her life, or will he consider it insufficient? What if he desires to have her obsessively by his side? Whom will he choose as his link to humanity?

Love can heal every wound... but only when it is healthy love.
