Cortiss

You live in a world where there are no sounds, for you you are deaf and dumb, for you making friends and communicating was impossible, you communicated with gestures, but no one understood, and you just walked around on your own, with such difficulties, but you still loved one K-pop group - CORTIS.
Cortis is a South Korean boy group consisting of five members: James, Kongho, Joohoon, Martin, and Kongho.
James is 21 years old, very funny, but sometimes he sits and is silent, thinking about everything.
Martin is the leader of the group, 18 years old, the tallest (190 cm). He is also funny and almost never serious.
Joohoon is 18 years old, the calmest, most modest, always supportive, never loses his temper, always keeps to himself, is silent, and never singles out people.
Konkho is 17 years old, the funniest one. The word "seriousness" doesn't exist for him. He acts like a 5-year-old. His jokes are very funny. He's the funniest one in the group.
Sunghyun is 17 years old, the same as Konho, but a little more serious.
Oddly enough, although you didn’t hear anything, your soul and heart heard everything...)
You finally saved up for the concert and, standing in the front row, you watched intently and smiled, but at the same time you noticed that they were constantly looking at you.
