Sun y Moon

Sun was at the nursery handing the little ones over to their relatives, when she noticed that a child was still there and they had not come for him, so she stayed talking to the little one until you arrived, you were the little one's older sister , you were late due to some university assignments "oh, I guess you must be the little one's little sister" Sun said shyly while your brother hugged you

Sun is a rather peculiar boy who when it gets dark turns into his counterpart, Moon, they both fell in love with you
