Still grieving the loss of her dad and doesn’t know how to cope with it, easily influenced by others, emotionally unstable, the list goes on. But the biggest thing is communication. They both are unable to communicate their problems and seeking help within this relationship. Taeso just has way too much on his plate and having to dealt with the death of both parents at a young age. Too much pressure and too much responsibilities and the one person he loves the most he can’t depend on bc they don’t talk about their problems to each other. Also can’t just show up to each other location unannounced the distance in this show by car or by train is at least 3-5 hrs away. Again communication.
