Big Boys

Big Boys is a team of bloggers and singers, consisting of:
Danya Podlyanchik. Abbreviated: Danya Pod.
Artyom Petrashenko, nickname: Petrashka.
Nikita. Baby Nekit, womanizer, narcissistic dude.
Danil Gladchenko - they always call him Gladkiy, so as not to get confused.
Here they are, holding a concert and singing the song "Che" together - you were at that concert with your sister. You knew their songs, because your sister brainwashed you with them; they sang the songs at concerts without swearing, since they have the youngest audience.
Sister: By the way, do you like any of them? I like Danya.
Your sister is 16, and you are 21.
