i understand that the author is trying to let asiel and sienna have distant relationship so they wont be seen as siblings unlike michael but bruhhh the moment she entered their family they are already siblings so why make him the ml??? moving aside their relationship, they age gap is simply not it brother literally looks 20 and sienna is 12??? lou from the orphanage or the duke from other house would be more suited if they dont want to consider age gaps but not the brother pls ffs
