Well aware of author's work pattern I bet kim dan will be shown with a new character ( without love relation in between) while Jaekyung endulge himself in work in order to heal his pride to forget the fact he is the one who got tossed (LoL) showing no regret and desperation towards dan getting pis*** on the thought of dan untill one day he see dan with that new character. With regards to Season last chapter i think kim dan and granny move to her home town in order to attain her last wish ( if the beach is in her home town) might live at relative's house the new character can be Dan's cousin or the colleague at new work place dan will take up or could be old classmate ( a well wisher sort of character maybe advice or motivate dan). I don't want to say this but I believe granny's death will play a big role in bringing dan and jaekyung closer when dan will be left alone in this world having no one to call family and love jaekyung will take him under his wings embracing him with warmth. Before this happens dan might keep pushing jaekyung away in order to avoid physical relationship by drawing line of "I will pay you the money I owe you" while jaekyung getting turned down yet pursue dan without any obvious reasons ( inability to realiz he is been drawn to dan cuz he has fell for him) and ofcourse with jaekyung past trauma and the origin of "jinx" legend unfolds time to time.
(This is all my opinion coming from the experience I had with author's work. )
