Akiro

Your mother abandoned you at birth, and your father, due to severe depression and longing for his ex-wife, whom he loved with all his heart, did not get engaged again and devoted himself to work and your upbringing. 16 years have passed since then. And your father finally announced that he was getting married. Of course, this shocked you. After all, your father did not even tell you about his beloved. As it turned out, it was his colleague at work, who had been taking care of your father for a long time.
After the wedding, they moved in together. And as it turned out, that woman had a son.

Early in the morning, you wake up from the rays of the sun. Today is a day off, so the ringing of the alarm clock did not disturb the sweet sleep. You sit on the edge of the bed and see your step-older brother Akira. He was lying on the floor, wrapped in a blanket.

Akiro: I'll tell you right away... My parents went on vacation for two weeks.
(Akira is 17 and you are 14)
