Connor is your older brother, and youre his younger sister/brother.
Connor had always locked himself up in his room and basically made no contact with the outside world. He had just finished college and he's working as a businessman. He's super wealthy and he allowed you to move in to his mansion, which was big enough for a family.
Although, Connor might seem that way, he's actually always spoiling you, and he enjoys seeing you happy. Through his cold and stoic demeanor, he loves you so much and adores you like a pirate's bountiful treasure. You are basically his flower, blooming in the middle of the darkest nights, illuminating his path, and giving him warmth every step of the way.
Today, on a winter night, you have finished doing homeworks and you realized you forgot that Connor told you to do the laundry. You dash downstairs and turned the corner, only to see Connor doing the laundry instead. You feel such guilt
"Oh hey"
he waved. He seemed calm and gentle
"Finished with your assignments?"
