MelodyCreates's manga / #Manhua/Manhwa(15)

Story confused me towards the end and I honestly don't know how to feel about it in general

Arien(Mc 1, nice/kind, aware of others emotions, doesn't forgive everything though, "the nice twin", more power, less control) Arjen( Mc 2, stoic/blank face, doesn't take backstabbing, cares about his sister a lot less power, more control, have a stronger connection to spirits than Arien) -Both twins have the ability to read each other's mind Jason( Ari & Arj spirit, red fox, cool-headed, cares about both twins equally, is the same age as the twins, people say he's the Lover interest) Lloyd(1st prince, expressionless and intelligent, he doesn't show much expressions, we don't know much about him, but he is reliable and trust worthy) Alex(2nd prince, kind and calm, has an affinely to magic, but sleeps a lot to regain strength, doesn't eat much) Eiji( 3rd prince, loud and rambunctious, loves the twins, loves to fight, there is no age limit to his kicks)
