Wendy was neither happy nor sad. Hot nor cold. Hungry nor full. This was how it had always been. Nothing ever really had a big impact on her. She had never been upset or afraid or angry, and she had never been excited or thrilled or interested in anything either. She had no favourite animal or food or colour. She was just plain old Wendy. 

Seulgi, however, was the exact opposite of this. She was a very sensitive person. Even very little things could have a big effect. Her favourite thing was to go out walking in the rain. She loved the thumping of the rain against the ground, the feeling of the cool droplets against her skin, the scent of the fresh green grass. To Seulgi, the world was a beautiful yet terrifying place.
