I really liked this current chapter, its non chalant yet great. I very much prefer for them to part in this way and then later on, meet up in a better circumstances and sort out their issues and become good acquiantences.
BUT, we all know thats not how things would pan out, they'll defenitely give into the audience pressure of reuniting them. Possibly by using Dan's grandma's death, where Dan would have to handle the funeral all alone after learning about her death, here comes the savior, Jerkyung!! Who'll arrange the funeral and help take care of issues and Dan would weep on his shoulders and cue the Dan's past and talking and Jerkyung asking forgiveness and starting a relationship.....
Even if the story uses grandma's death as another reunifier, I still prefer both of them rather become good acquaintences, perhaps Dan settling in that town and working there as hospice physiotherapist and becoming visting physiotherapist for the gym and all that. For me, the relationship is far too much damaged for them to get romantically involced, but still redeemable enough for them to remain as friends
