The two main heroines of this story have deep ties to the MC who himself doesnt realize or remember it at first. For Finne, he actually met her years ago when she was young and he gave her advice when she was about to be presented to his father the Emperor and how to overcome her fear and anxiety for that meeting and event. She admired him ever since as she views him as someone who cares for others (Chapter 118 of the novel). When Al met her father in this chapter and later was identified as Silver, she saw he was the same boy she has known for years and wanted to repay his kindness. The other heroine yet to be introduced, he went to prison for as a young boy.
