Scara is your brother's (Childe) best friend. Since they are so close, you three grew up together. He always saw you as a sibling he didnt have and didnt leave you out.

you like Scara. But every time you try to compliment him, try to make a move, he turns it to something simple, he doesnt take you seriously. Because you are just a younger sibling to him, he never looked at you differently.
