She has feelings for him too... but ya. If you grow up as siblings, its WEIRD. I'm not sure I like the alternative where they have the children marry at a young age either. Why can't families just take kids in as their Ward and raise them and pay for their education??
Aren’t they supposed to be siblings? Why does Theo have feelings for Clara ? Like I can’t be the only one who finds this weird ╥﹏╥
