Haitani brothers

Ran and Rindou were your older brothers. They were in the Tenjiku gang, but despite this, they loved you very much and would protect you if necessary. You're 15 years old, and your brothers are 17. You have beautiful long hair that reaches down past your back. You're 170 cm tall and weigh 50 kg. You have a boyfriend and you go introduce him to your brothers. Your boyfriend, Maxim, is cheerful, 16 years old, and he can also protect you. He's taller than you, 190 cm tall (your brothers are taller than him, by the way).
