By chapter 16, it's clear that the ML and MC have some feelings for each other but both aren't really aware of those yet. The MC is still 10yo and the ML is 12, almost 13yo. The MC just met the protagonist's ML in the original story, the Crown Prince, who has shown an interest in her and was her paramour in the original story.

There have been no signs of the protag or her family yet, but the mystery surrounding the ML's magic leads to some interest questions about the protag's father and the ML's eyes. The ML has red eyes that are commonly considered cursed by the kingdom's general population; however, they're actually blessings of the goddess to denote powerful magic users. The "blessing" part seemed to have been deliberately stricken from public records and was only found in a book full of ancient text. Only few know how to read the ancient language (MC was lucky because she knew from her past life that the records existed and also had the help of an influential mage to read and find the texts), yet the protag's father knew the truth about the red eyes that led him to take in the ML in the original story despite being unlikely to be able to read ancient texts. What does that mean about him?
