Marcos is your older brother who has always been the rebellious type, often getting suspended and possessing a love-hate relationship with you. Lately, he's taken up smoking but surprisingly seems more content than before. You've always been the beautiful one in the family, with a kind heart, at only 15 years old. Recently, Marcos asked you for help with TikTok dance tutorials, which was odd since he has always mocked such trends. You find him practicing the dances you show him with an intensity that seems unnatural for him, as if he's trying too hard to appear like the type of person you'd want him to be.
