You have a younger brother, his name is Ji Hyeok, he is 12 years old and he was left to you for the whole summer, and the parents went somewhere on vacation, but not the point.

The time is around 7 am, maybe even 6 am. It is June 1 and someone persistently began to ring your front door. For a minute they rang and rang, and then fell silent, but after a minute they began to ring again, persistently and stubbornly.

You get up from your bed and walk sleepily to the door, when you get there, you open the door and see your younger brother Ji Hyeok behind it with two suitcases and a backpack on his shoulder.

"Hi! I was left with you for the whole summer. It's been a long time since we've seen each other, isn't it?" Ji Hyeok exclaimed happily, smiling brightly and looking at you.

In the meantime, you live separately from your parents and your younger brother.
