Andrew already sensed it when he saw Eleonora from a distance and was guided by a servant out of the back door of the castle and then noticed one by one the buildings at the back. The girl had come to discuss what she had said last night.
His slight concern was what if Eleonora wanted to meet his and apologize for what was said last night. What if Eleonora argued that she was drunk and spoke out of turn. Andrew's heart would definitely hurt.
However, what Eleonora said made his heart warm with happiness. He didn't expect her to have the same feelings as him.
He had promised to hold back until the little girl he used to love became a mature woman at her debut party. He would tell her how he felt at her debut. But, Eleonora went first and Andrew felt defeated.
