Kingdom of Stars, Sword Flower University, evening.
Carrying a sword bag, Ingrid returned to the dormitory and lifted the gold-edged invitation in her hand, "I just came back from a practical swordsmanship class, and someone entrusted me to deliver this invitation to Sonia."
Adelle went over to take a look, smirked, and casually threw it into the trash can, "A mere Viscount dares to send an invitation, really a toad lusting after a swan's flesh... Ingrid, let me teach you, for invitations like this with less than three stars, just say 'I'm not very familiar with Sonia' to refuse it. If there's a Moon Star, then you can bring it back because that means the sender is at least a formal heir of an Earl or higher."
"What if there's a Dazzling Star?" Ingrid, although of noble birth herself, had never studied heraldry since childhood and knew nothing about noble etiquette.
