There are a lot of very nuanced relationships to navigate in this IF, which makes it very fun to RP in. I did not mean to write a small essay but this IF has so many fascinating setups lmao I have brainworms (minor spoilers below)
The relationship between the MC, Lancelot, and Luceris is extremely interesting-- at moments, Luceris often even seems fond of his "bird", whereas Lancelot is very protective of the MC (and seems to have a deeper relationship with Luceris?). The MC I play feels caught between wanting to forge a deeper connection with Lancelot as a guardian figure but feeling betrayed by Lancelot's loyalty and affection for Luceris, realizing that a Shield's first priority is their king.
There's a similar potential divide felt there with Hunter, as they're Helios's Shield. When and if it comes time to choose, there's a hint of uncertainty: will Hunter side with the MC, Helios, or Rosea? Does that affect how close the player allows their MC to be with Hunter?
Also very intriguing (and the most potentially angsty route) is the relationship between the MC and Helios. It's been fascinating to see these glimpses of Helios's personality and personal philosophy growing up. The MC often compares him to his father, but is his personality all that different from Luceris's prior to the consort's poisoning? Add on the fact that his appearance grows closer to Luceris's by the year, reinforced by its effect on the MC in the latest update, well... Moreover, it's doubtful that Luceris would approve of a budding romance between his two wards, or really, any romance involving Helios based on his reaction to the duke's child, though his thoughts on friendship are more obscure.
Then, finally, the underlying theme of revenge-- is letting go and being happy the best revenge, as people say? Is finding the truth and potentially clearing your family name the path to catharsis? Would striking Luceris be enough, or must all his collaborators fall as well, even when that list includes Lancelot? Could the best revenge be turning Prince Helios against his father... or even, destroying the prince's heart and trust in a twisted bid to have Luceris watch his son fall to ruin? And if Catarina and your family really did set things in motion somehow... what then? Does it shift the spotlight of the MC's ire?
