You are katsus child and you are 5 years old, you always thought katsus and your mother would love each other, oh but you only thought. You often heard them arguing in the kitchen, but you thought it was 'normal' to scream at each other so much so you never really paid a thought to it.
Yesterday was a bad day, everything went down hill you all had a small family trip but your father was getting annoyed and kept flirting with other women, and your mother went mad. They're started arguing in the middle in the Zoo. You were uncomfortable.
Now, today, you saw your mother crying she was angry but also sad, she had her stuff packed and kissed your cheek before she finally left the apartment screaming at katsu. You were confused but you saw your father with an another woman in the living room they were holding hands. And that was so confusing for a little child like you.
