Like you didn't understand me at all. I didn't imply anywhere that the longer relationship is more stable. No. But it's rather obvious the longer relationship is you face more issues, problems and have more experience with the other person.
So it's hard to compare relationship which lasted decade and point out every bad experience and action with one which just barely started.

It wasn't just the parents who were the problem. In these circumstances, what people would do was end the relationship and pretend that nothing happened. But the two got worse and continued to have sex without transmitting affection to each other. If I were in their situation I would do ...
1. Or would immediately end the relationship and forget.
2. Or would date in secret.
But the two did neither. They've been in a relationship that can't even be called dating.

I never said their parents where the only problem. But IMO they are the main one. Even in their subconscious they still believe they are doing something bad, taboo. It's imprinted in their mind. Haesoo's mum said herself: anyone but Joowon.
Dating in secret is never perfect solution especially if you feel your relationship can destroy your family and you are living in lie. That's why imo they never went further.

That's why I think that if they never planned to date, then they shouldn't have started this relationship.
(they themselves, in that interview at the beginning, answered different things to the question: "What kind of relationship do you have?"; this just shows that the way they saw the relationship was different).
Guys, I'm going to make a very long text because I really need to say this because I feel my heart is broken.
Most people who are against Jowoon say that they are siblings so it's toxic. Using that as an excuse doesn't make sense. I've seen hundreds of stories where they even involved real siblings and yet I was in favor of their relationship.
I'm from #teamTaku but the reason I don't like Jowoon is not because they're siblings but because I don't like the way he says he "protects" Haesoo.
Some time ago I read a light novel and two characters started talking about a couple who ended up breaking up.
One of them said: "If he really liked her but in the end they separeted, then it only shows what they had was only 'like' ".
An the other responded: "Things aren't always that absolute. Sometimes, it's not up to you to decide if the road is easy to walk".
An then the other said: "I might not be able to decide whether the road is easy or not, but whether I walk it is entirely up to me".
Both Haesoo and Jowoon were cowards to even try to resolve the situation. They didn't even think about solving it. It is as if, for them, that was already decided. It is ridiculous to be quiet and wait for something to change without taking action.
Also, even though Jowoon was worried about Haesoo, I can't forget that he once said, "You can't live without me, even if you're in a relationship now, you're going to break up with them and come back to me" ...
and also said: "If you died, nobody would be with you". (I no longer remember which chapter it was in).
This is painful to hear. Imagine that the person you like says things like that. Really hurts.
I can't understand why people want Jowoon x Haesoo when none of them showed real affection for each other.
I no longer care who Haesoo stays with but if he stays with Jowoon I will be disappointed by the character.
Someone said, "Going back to someone (ex) is like opening a book that you’ve read and you know the ending."
It's sad.
What will hurt me the most if they stay together is that I will feel that the Taku was only used as a springboard for these two to be together. He is a good person. He deserve better.
(my english is really bad, sorry)
don't hate me (my heart is in pieces and I needed to discharge my frustration)
