Eclise is angry at this situation. He's from a land that was defeated, he watched his family and his countrymen die and now he's a s*ave. There's this woman who tells him she wants him to be hers and gives him things, but her eyes are dead when she talks to him. She demands his attention, his love, his devotion without giving anything in return. Now think about this, due to the game that they are in his stats are starting to rise even though he doesn't like Penelope or this situation. But he starts to love her.
During his time with Penelope, he's left alone the majority of the time. Penelope breaks her promises with him almost all the time. Outside of one or two incidents where she helps him, he's mostly seen as a punching bag for the other knights of her household. He can't fight back, he can't speak out, he can't do anything because of his status as a s*ave. He's also the youngest character in this story, so it's kind of depressing to see him in a constant amount of pain just to prop up Penelope.
Prop up sounds weird, but that's exactly what happens. Due to a mixture of the game brainwashing and Yvonne's brainwashing, Eclise becomes obsessive with Penelope. He wants her for himself and wants to help her, since she's always has dead eyes whenever he sees her.
He ends up dying after Penelope casts him aside. The way she does it is meant to come off as a boss bit*h moment, but it's so cruel when you remember that he's a young kid who is desperately trying to hold onto the only person who is kind to him, even when that kindness has ulterior motives. He has no one else, because they're all dead. Then, he's brainwashed.
The way Penelope and the story treats him made me angry. Penelope is told on multiple occasions that she looks dead when she's talking to people and yet everyone loves her. Why? I get if they pity her, but why love?
And that is why I have an issue with the story. There's a scene where Yvonne just tells Penelope that if she told Eclise that she likes him, he would have calmed down. But Penelope says she wouldn't do something so hateful.... meanwhile I'm here thinking "If you knew that this was going to help you get to 100% you would have done it in a heartbeat, because you don't care about anyone in this story."
Yvonne calls her out on this and pretty much calls Penelope a hypocrite, but the story keeps hammering in the point that Yvonne is wrong and Penelope is right and that's the way it is. So tell me, why is it wrong for Yvonne to brainwash people, when the game allowed Penelope to do something similar in order to save the world? I get that Yvonne wants to destroy the world, which is bad, but if we ignore that part (LOL) what is the difference here?
The way she treats Eclise is manipulative and abusive. She reminds me of those parents who knows that the other parent is abusing their kid, but ignores it. Then they swoop in and say "I'm still here for you." While enabling the abuse to continue. Eclise is not only a s*ave, but a kid and that kind of power dynamic is ignored in favour of writing a yandere character.
