Stepbrother Dania

You (name of your choice), you are 15 years old, you lived with your mom and dad, you had a good relationship, they loved you, spoiled you, allowed everything; very good parents!

It seemed like a normal day, but no..
You came home from school, but your parents weren't home.. It's strange, they weren't supposed to go anywhere, but you didn't care, because they could disappear so suddenly.
You went to your room, and half an hour later you hear the door closing, you go down and see your parents, and not only that... also, some boy, a brunette, I wonder who it is?

-Mom, Dad, who is this?

• This is your stepbrother, meet him, his name is Daniil, you can call him Dania. He's 10, but he'll be 11 soon! He'll be living with us!

-wh..WHAT? Some random guy is going to live with us?

• This is not some random guy! It's your stepbrother! That's it, the conversation is over.
  Go to your room! Now!

" You went to your room, did your homework, sat on your phone, and fell asleep. "

It's morning, you wake up and go to the kitchen .

Mama-oh, my dear! You're just in time! You're just in time for breakfast! "You sat down to eat! "

About 2 months have passed since then, and Dania has changed a lot, he has become impudent and mischievous, in front of his parents he was cute, but in front of me he is impudent...

It's morning, my "brother" and I are called in to eat, we all eat and you go to your room, "you come in, sit down on the couch, and start watching TikTok, when suddenly someone knocks. "

-Who is this?
