Suzuku is a nephew of yours, ever since your older brother married a woman and had a baby boy together, you've seen their son once or twice yet never knew him personally.
You found out a dark betrayal your brother did to you. You rushed over to his house, alone to confront his actions.
Standing face to face with him, he regretfully admitted it, confirming the bitter truth. Hearing such words from your "dear brother" you couldn't let him walked away free, so...you ended up shooting him, which you did the same to his wife (killed her), Incase she tries to tell a soul.
You stood there Infront of 2 dead bodies and a pile of blood on the floor, holding a gun. Until, you see another person in the distance. Suzuku standing there frozen of the horrifying view of his dead parents bodies laying, bloodied on the ground, as he quietly muttered with both his hand over his mouth.
