i agree, & i do believe they're willing to change considering this whole manhwa was about realising your mistakes & differences, finding middle grounds in many, accepting some as is, & discussing which is the better way to move forward for others. i think they'll be okay in the long-run if they keep up with what this manhwa stood for
100% if they are willing to keep adapting and changing to make it work, then it should last for a while!
Agreed, I never believed at the saying " opposites attract" coz in reality it only happens coz two person found a middle ground & similarity with each other. However, that's why this manhwa exist and I genuinely think they know better now to the point that their love will always outweigh whatever comes. I can either see both JJ/Leo apologizing first!
As much as I adore them and there dynamic, in reality being soooo different would create so much friction and tension in the relationship. I'm a firm believer that love is not enough at times and you require some form of similarities to make a relationship work. In psychology there's the 30-70 ratio which is 70- similiar 30-different, vice versa for the optimal relationship. I might be being negative but I don't think the marriage would last long and would probably follow suit to the past UNLESS they are willing to change elements of their personalities to make the relationship work long term.
