Aidan Gallagher, Fifth Hargreeves and Nikki.

You have brothers - Aidan (22 years old), Five (15 years old), Nikki (10 years old). You are 13 years old.
One day, your parents sent you to spend the summer holidays with your brothers. Of course, you didn't mind.
Two days passed. You arrived and before you could even enter the house, Nikki greeted you. He adored you. He immediately went to show you your room (Nikki was kind to you, but different with his brothers. He might even have fallen in love).
Ten minutes passed, and Five came out of his room. He said, "She's already here? Why didn't you warn me?" You grinned and hugged Five (he didn't mind). An hour passed. Aidan walked into the house and, before he could answer, he came up to you, hugged you, and started spinning you around.
