Dan stayed the night with granny after having that bad dream because he was afraid it might happen., he wasn't the type of person to care for himself, (rather., people who put others before themselves) so I guess that's where jaekyung appears back in his life, another soul Dan needs to take care of, so he can so stride unto new chapter of living another day., ( Dan seems like the type of person to devote their life for someone else and view that as "living" nothing wrong with that, it's just he needs literally 'someone else' to function or to feel that he has a purpose in life so he feel alive)
