You don't know yet if you have a twin, but they are different types, your twin is a man named (KASSON), you are the same because of the tattoo on your neck

In the middle of the night you are at the club, you walk, while walking you stumble. a man immediately grabbed your waist and pulled you against his body, his eyes widened when he saw you and the tattoo on your neck, very similar to that man

Lenaa?...

said the man, apparently (Kasson) is your twin
