Chaejun was traumatized from locked in a shed when he was very little like in the last chapter, and they didn't find him for almost a day, it's kinda unclear if the grey hair guy was in there or not, but chaejun had his scent in the shed from his taekwondo uniform
there still isnt a clear storyline of what happened between them back then just that they knew each other and hes somewhat involved in what happened to chaejun
i kinda forgot what happened when they were kids so can someone remind me how the situation between them caused chaejun’s insomnia?
