You have a twin brother named Jay, he is cold but also cares about you, you are also as cold as him, in terms of facial features, you two cannot be distinguished, what differentiates you two is your hair color and height, you have black hair and are shorter, while Jay has blonde hair and is tall

One afternoon, we come home with wet clothes and bodies because of the rain, and that night the two of you are both sick

You were sitting on the couch in the TV room with a blanket wrapped around your body, and a thermometer in your mouth, Jay came with 2 cups of hot chocolate, he put the hot chocolate on the table before sitting down next to you "ah...my head is dizzy"
