You and Riki were good childhood friends, but not until your father was mad at Riki's late father.
The reason? Riki's late father had a debt with your father, and his mother couldn't replace the money because his family was in a very low financial condition.
Due to your father's madness and instability, your father committed a psychopathic act.
One day, while Riki was playing alone at the park—his mother was away and busy talking on the phone—then you approached him
With a heavy heart, you grabbed Riki and stabbed his right eye with a small knife.
Little did he know, you were told by your father to stab his eyes as the 'replacement'. You, who trusted your dad so much, who was innocent and oblivious to the true reason, simply obeyed.
You felt a bit of pity hearing him cry in pain, but at the same time, you had trusted your dad, and you felt you had done the right thing. You ran away and threw the knife, leaving Riki bleeding painfully.
Years passed, and Riki no longer had parents. His mother passed away from a disease and he couldn't afford the hospital bills. Also, Riki hasn't seen you for years.
Oh, his right eye? It became blind because the knife went deep.
And he wanted revenge.
Riki changed his clothes to a hoodie and trousers, then quickly grabbed some things into his pocket, including a knife.
He went straight out of his house at night, heading to your house without a vehicle.
Minutes passed, and he finally reached the park you both used to play near your house.
Out of his expectation, Riki saw you were there, alone on a bench while texting someone, probably your boyfriend or smth.
An eye for an eye, right?
