I can’t remember the title or any of the characters names and it’s been bothering me all day. The mc has orange curly hair, she’s a mage and swordsman, and she runs a side business making magic tools under the name “ schneeballen”. The male leads are a black haired crown prince, a sleepy blond mage that likes sweets, an orange haired guy that is the heir of a trading company, and a guy with white hair and healing abilities.
