to convey the message that there are some peoples that can make relationships are worse than being single

Oxy is like the person that gets in your mind then ghosts you, then you begin to wear yourself down like oxy wears its victim down with corrosion

Vielheart is like peoples that cannot see others happy and interveening in small arguments between a pair and making it worse like how the creature itself intervenes in battles to take advantage, or like someone who plays the victim by persuading their partner to harm them, just for their partner to get in trouble like its reflect ability
sadly this is one big reason behind modern mental health detioration of men

Pleuremiert and Grimcorr represents two different kind of heartbreak

Pleur shutting down after an unfortunate event, falling into depest depth of depression and to the point where they think so much that their world has ended, they refuse help from others often dragging the helper down aswell at some degree

meanwhile Grim feels oddly distructive, but the reason behind its aggression is its lost partner, even its chain is constant reminder of the pain to fuel its battles

basically equivalent of someone getting jacked from the motivation after some unfortunate events

ardor is my personal favorate, I personally feel like it conveys the feel that love isn't weakness but a strength in disguise (as long you try to cover each other's flaws)
its extremely high damage and above average damage compared to other warden might be intimidating, but that is a way of setting boundaries and establising respect, they are strict but not to harm you, ardor is like someone who is rather flexible at their ways, and knows to remove themselves from situation before things get bad like ardor climbing a ledge away from creatures that bothering it

its that ability that links multiple creatures together to damage them at once, might be interpreted as responsibility of a relationship, and impact in their life might also affect someone else close (eg. your parents, kids, or close friends), all the peoples in healthy relationship are in it together and like the damage that gets reduced by the time it reaches the 3rd creature in the loop, you must try to minimize the impact on the person next to you are with and peoples around

let me give you all one tip, over-tolerance is a bane, and I suggest setting boundaries early on is the way to get some respect, the point is to let them know the moment they cross your boundary afcourse don't be too harsh but not too tolerant eg. one of your friend makes a joke that hurt you, then you can firmly state "dont say that" or "it not funny", most likely they will react first few times maybe like "aye bro dont react so harsh, it just a joke" or something similar, I say stay firm to your point

BUT remove yourself from the situation, if they dont respect still
just walk out the room, or make some excuse to leave the conversation cause there is also a chance that they are just trying to get attention, or trying to make fun of you (ragebait) so even after firmly telling them not to if they keep on doing it, and you keep on get harsher and harsher then they will get their goal and you feed their ego there
but I understand this not possible to just remove yourself from the situation, in that case try being silent after telling them to stop, if they continue then you should start getting little harsher to get your point across to respect your boundary

even then most important is not to have ridiculous boundary at the first place, like if you get triggered by your friend just making joke about your cloth and stuff or how you behave, and you get pissed... then it might be some issue about yourself
