It hurts my heart to say this but I think Gun and Hanmi will break up in the probable future. Some people are together because of their similarities, and some because of their differences. There could also be some because of both. But Hanmi and Gun's similarities and differences aren't helping their relationship improve. It's just making their relationship take a turn for the worst. Ultimately, I think they are more similar to each other. They have someone tied up to each of their own. They can't let go of the past and it shows that their relationship isn't very important to them (it looks like that to me). There are interactions but it's kind of not enough. Even when they're with each other, they're both thinking of other things. They're actually more like ideal types of each other. Just ideal, not real. But all of it could change in the next chapters. I could be wrong about this but this is just what has been on my mind recently.
Will never get tired of re-reading this╰(*´︶`*)╯♡
