I don't want Haero and Don to end up together.

But is too toxic, and they will eventually break up again. But you know what pisses me the most? The fact that they decide to be together after meeting BY CHANCE, where was all their devotion before? Did they accept their lives separated but as soon as they got together, pam! "I have always love you, I can't live w/o you". It sounds so fake now.

I felt like they'd grown used to their daily lived without each other. A bit like how you get used to being away from home after a while but, once you get back, it's even harder to leave than before. Could they have lived without each other? Yes, they did for ten years. But could they be truly happy, without having even properly talked it out? I doubt it. I don't feel it's fake, but rather that time got them sort of numb until they met again.

How do you know they’re going to break up again? They were 19 and Haero basically was told he would cause troubles to Don all throughout his life by his own lovers ex that he was secretly meeting with. It’s just communication and understanding. He said he moved away and changed his number how was he going to find him? Plus he already was having family issues with his mother the last thing he was should I continue to break my heart that’s already broken. He has sand has a lot on his plate. Life wasn’t gone stop just because he was heartbroken. You have to accept being separated because as you see life moves forward They both still loved each other for them 10 years. This is the time for them to work and fix what was broken. That’s just how life is sometimes. If Haero didn’t come back Don would have halfheartedly married Nami

People choose to live when they know their going to die so why can't they date knowing that they might break up? No relationship is guarantee. And no relationship end up with a happily ever after. In fact, all relationship ends with tragedy. Either through break up or through death. That is the reality. Yet, people still choose to love each other anyway.
Honestly, I don't know why you would even use the word "toxic" to describe their relationship. You make it sound as though their relationship is hazardous to other people or they'll only be miserable together. Fact is, they're not going out of their way to hurt anybody. And they might be miserable together but they will also be happy as well. Which is practically the same to all couples no matter how loving they are to each other.
And they didn't just move on with their lives and then become passionate again once they meet each other. They obviously never got pass their relationship and was holding in all this time. It's not strange at all as to why they would react the way they did once they reunited.
I agree with you that they were stupid and don't know how to work their relationship. But to say that they shouldn't be together because their relationship doesn't make sense is a whole nother matter. Their relationship was develop and so was their character to explain that relationship. They're not Sakura and Sasuke.
Honestly, how they hell did those two fall for each other? I can't believe I'm saying this but Sakura and Sasuke's romance development is a worst love story than twilight.
Please explain gramps.
