Relationships
 Kingdom of Sunkland 

Echard Sol Sunkland: Sion's younger brother who has an inferiority complex. Sion knew that Echard is not as competent as him, but he still cares for his brother and hopes he learns about things around him.

Keithwood: Sion's trusted bodyguard and valet. It is stated that they grew up together like siblings.

 Saint-Noel Academy 

Mia Luna Tearmoon: The relationship between Mia and Sion is a complicated one, with him being the hero who issued an execution upon the tyrannical fiend, Mia, in the first timeline and her still holding a (minor) grudge against him in the second timeline. In the first timeline, Sion was disgusted at Mia's behavior while Mia believed that they were meant to be together. The prince always avoided Mia to look for Tiona and was extremely annoyed at her persistent. Although he supported Mia's execution, he came to regret it later in life.

In the second timeline, Sion is in love with Mia and he finds himself charmed by her wisdom and intelligence. When he sees Mia works hard to change her empire, Sion is inspired to do the same. They trust one another and come to each other's rescue when in pinch. Their friendship is something Mia never had in the previous timeline, and she sees Sion as one of her dear friends. After Remno Revolution, both Mia and Sion dropped their royal titles and address each other by their first names. Sion likes to tease Mia to get a reaction out of her and he initiates his moves on her such as being the first person she dances with at her birthday ball.

Tiona Rudolvon: A friend of Sion. In the first timeline, he and Tiona were the prime figures who had Mia executed. In the second timeline, they respect each other as friends. Tiona encourages Sion to make a move on Mia when he still can and he considers it.

Abel Remno: Sion's friend and rival. They spar with each other when there is a chance, such as during the Swordsmanship Tournament, Remno Revolution, or in their free time alone. Throughout the series, the two friends have a casual relationship and both threw away their princely titles and address each other simply by their first names. Despite being in love with the same person as Abel, Sion gives his friend pushes if necessary. Abel is also someone whom Sion is jealous of for Mia's attention and affection.

Trivia

 * Sion is older than Mia and here is that evident. Sion's birthday is still unknown to readers, but in Volume 9 when Tiona asked him when was his birthday, he replied "10 days ago". The annual season in Volume 9 is summer. Mia's birthday is in the winter, so that makes Sion a few months older. Plus, Saint-Noel students attend school in spring the year they turn 13, so that makes Sion already 12 in volume 1 and turning 13 in volume 2.
