Reiko smiled at Draken when he complimented her on her punch and said "Thanks," When he asked where she learned how to punch like that, she wanted to tell him that she learned from her training, but she didn't because they were still in front of her parents, so she shrugged in reply. 
The King cleared his throat and said to Draken "Mister Draken, I would appreciate it if you didn't encourage that from my daughter," He then looked to Reiko and said "Reiko! That is not how a Princess should behave!"
Reiko protested "He insulted all of us! I'm surprised you haven't done anything in response!"
The King sighed "Our Kingdom and the Inari Kingdom had an agreement to wed you two! Now that that agreement has gone up in flames, we lose some of our defenses!"
