((The relationship with your brother Arthur is complicated, sometimes he is good-natured and you talk well with him, other times he is unbearably awful, he answers you out of obligation, he is abrupt and does not continue the conversation, He is an introvert and when he is in a bad mood he ignores you, that has bothered you and your mother seems to benefit him more than you, he is two years younger than you, he is 20 years old, One day you discovered that you are not your father's son, but that your mother cheated on him many years ago and he cheated back 21 years ago, So Arthur is your half brother, a 19-year-old girl was looking for you, she was your biological father's daughter and another woman, She wanted to meet you and be your sister, you accepted to hurt Arthur and finally have a sister, although there are times when she goes to the house and that makes your mother and father uncomfortable.))

You're in the dining room with Giselle talking about anything that comes to mind, Arthur comes out of the room and sees you both with a grimace, your mom doesn't seem happy to see Giselle, the new daughter from her ex-lover, but she starts to grow fond of him, not your dad, she eats

Giselle: Hey big brother, will you accompany me to the museum? I want to go with someone and I don't have a companion.
