my heights have truly been wuthered

Ray lost, he failed, and anyone who came after them was doomed to the same outcome.

Unknown, or rather SE Saeran now, suffered to the brink of apathy. There was no room for emotions in his heart, only pain. Suit Saeran wouldn't be happy to learn about that. He's always put their safety at the forefront of his actions (even if his methodology hurt them, it was the only thing he could think to stop Rika from hurting them MORE). His role was rendered worthless, and now he doesn't know what to do with himself.

SE Saeran doesn't need him in the same way Ray did, but that doesn't mean he isn't going to try. He's going to attempt to make up for what he failed to do in the first place. He's going to make sure anyone who comes close to them isn't going to hurt them. However, this puts him close to Saeyoung in terms of emotional suffocation. Saeyoung is, for the lack of a better word, suffocating. His life's purpose was to keep his brother safe, and when confronted with the fact that his life was meant to be more than that, he couldn't take it.

He spiraled, pushing too hard, too fast, and it made SE Saeran fight back. That's the conflict I see between Suit Saeran and SE Saeran at their worst. Intention doesn't matter when it comes to impact. I'm not saying that Suit Saeran is going to sabotage relationships, but what I am saying is that Suit Saeran isn't going to make things super easy on whoever tries to come into their lives.

He's abrasive, meaning that he's the hard side of the sponge that tries to cake off the layers that get stuck to your dishes. The stuff that eats away at the stability and health of your plates! You're not going to win him overnight. You're going to have to show that you are a safe person for SE Saeran, Ray, and later on, him. Because he's going to dismiss his needs, as he often does, in favor of those he cares about.

If you try to strike up a conversation with him casually, he might ignore you. He might grunt, grumble, or turn away if you act like you're already good friends. How is he supposed to trust someone who says that they will be there for them when he's heard that before? The last person who said that is six feet under, and... SE Saeran can't sleep at night because of it. Who's to say you won't end up the same way? That's his fear, and it might take you a while to realize his fear isn't hatred.

It's the fear of grief, loss, death, erasure, and betrayal.

If you hurt SE Saeran or SE Ray by mistake, he'll close off any progress you might've otherwise made up until that point, too. He's guarded, and that's for good reason. He's upset FOR them, even if they aren't upset... and this makes for that conflict I was talking about a second ago. Ray may not be upset because he always clung to his other half, but that's surely not the case for SE Saeran. You go and approach him like you're Saeyoung, and it's not gonna be a good day.

They have spats, a lot.

You can't go between them. However, Suit Saeran will respect you more if you affirm SE Saeran's feelings. If you're SE Saeran's rock, if you keep him afloat and make him feel like he's an average guy, even after blow-ups happen, you're likely to garner his favor. He's not looking to see if someone will sit around and take conflict. He's looking to see if you're capable of handling how... messy they are. Again, it goes right back to his worst fears.

What if you can't take it anymore?

What if you leave one day and never come back because they're ruined and they ruined you?

What if he's ruined and he can never be okay again? What if he can't ever be close to another person because he's so caught up in being a protector that he can't see past his nose?

Because, at the end of the day, Suit Saeran WANTS. He yearns just as much, if not more, than Ray did. He just never felt safe enough to take what he wanted because he saw what Rika would do to them if he took one step out of line. Suit Saeran knows he's in the wrong. He just... he's got no idea how to stop being a protector. He's like Saeyoung. They've lost their original purpose and don't know how to move forward.

He's blunt, to the point, and never says more than he thinks he has to. He doesn't always know what's appropriate in conversations, so he has moments when he steps on someone's toes and sticks his head in the sand. Then he beats himself up in private because he doesn't like being this way. Why is he still doing this when there are no longer any monsters to hurt them?

Why is he the only monster left?

He's self-destructive to a point. He's afraid to be honest. Even if you catch him at a low moment, it will take a hundred tries to break past his shell. I do, however, think you can meet him there. You just have to be honest with him when he's cruel and hold him accountable. He wants that. He wants to be told he doesn't need to be mean anymore... but he doesn't know how to stop. He doesn't know if someone will have the right words to help him feel safe enough to move forward, but I think the only way to do that is simple.
