Kate had invited Ethan to have dinner with her in the cafe she frequently visited with Ciel and Chloe. It was a way to repay the kindness she had received from him for everything he had done. This included the things that the honest young boy did for her in the countryside.
To be perfectly honest, Kate had a very high opinion of Ethan. Although she hadn't met many boys her age, Ethan stood out among the rest. His easy-to-approach personality made him very likeable in Kate's eyes.
Both Kate and Stella agree that Ethan was the perfect example of a young gentleman.
"Go on, eat as much as you like," Kate said with a smile. "But, make sure to order only these dishes okay. I'm on a tight budget this month."
Kate pointed to the cheapest items on the menu which made Stella cover her face in shame. Although she was the one who gave Kate the idea of ordering less costly dishes for Ethan, she underestimated her other half's stinginess when it came to her pocket money.
