Ok...so far I am up to episode 14. I am very disappointed in the writers for not developing the HJP character more so. Is he merely there to be a fairy godfather to the main characters and to the grandmother. He is definitely not shone as a romantic lead, but a SIMP. He waited 3 years after professing his love and has yet to get a glimmer of returned feelings from Dal-mi? Sorry I would be moving on after not even 1 year. Did the character Dal-mi (in those 3 years) never reflect on all of those times HJP just happen to be there to support her in key instances. Was she that self-absorbed? What drives these characters? HJP is the only one who seems to be driven to help and care. If Dal-mi was not as pretty would he give up by now, what drives her. Don't we all want to be someone's FIRST choice and them to be ours?
If it end with Dal-mi and Do-san, it will be predictable and not in anyway satisfying. They do have chemistry, but the writers have neglected to give HJP character any equal time. More of a spectator in their story, which is sad.
In terms of a "start-up" it is not realistic. And SF weather is not all that.
