From the hand shape and skin color, it looks like two girls, and from the wrist, you can see that the person on the left is wearing a bracelet, which also shows that it is a girl. From the right, it looks like a girl with what is worn on the arm and wrist, but from the clothes, it looks like a boy. Anyway, it must be a girl on the left, but it is not sure on the right. It may be a girl or a boy, so it may be two girls or boys in the picture. You can only see the wrist, hand and part of arm in the picture.
