Light Chaser Rescue is a Chinese drama while Jirisan is a Korean drama (impacting their length). What they have in common is heroic rescuers that kind of make you want to become a rescuer yourself. Light Chaser Rescue is about a volunteer team and has no mystical elements. Jirisan is about forest mountain rangers and it has a ghostly melodramatic feel. Both FL are more cold whereas the ML are more warm, but Jirisan has romance only in the background unlike LCR which has it in the forefront.
Ghost Doctor is entirely comedic. Jirisan is entirely serious and mystical. Both have characters standing between life and death roaming limited areas as essentially ghosts. One lead actor appears in both dramas. While the vibe is entirely different, if you enjoy supernatural elements to emotional development stories that are more about life, some crime solving and a touch of romance in the background, you would enjoy both even though one is a comedy and the other a melodrama.
While Light Shop is more of a thriller with horror elements (nothing too crazy), Jirisan also shares a kind of mystical ghost presence. They also share the ML. Light Shop is about multiple characters and isn't a romance. Jirisan has some romantic elements but is ultimately about solving a strange reoccurring issue on the mountain. Both have melancholy and supernatural elements with deep love and affection.
Both have elements of love intertwined with past trauma. Both female leads are quirky and strange, and have a unique mystical talent (different ones in each drama). Both dramas are a mixture of a sinister past returning to the present yet they maintain a bubbly charming vibe. The male characters are emotionally cautious and closed off due to previous trauma. While both female characters also carry their traumas, they maintain a much more open and positive personality.
Both have a mystical element that ties the couple together with a mutual history that intertwines love and trauma making it bittersweet. Both female leads are quirky and "strange" but still have completely different personalities. Both male leads are emotionally closed off due to past trauma. Link: Eat, Love, Kill is more of a dark comedy whereas See You in My 19th Life is more bubbly.
Both have a mystical element and a bittersweet history of love with trauma and a lingering past. The vibe of Jirisan is much more serious and mystical, but sweetly enough, I am convinced they even filmed a scene in the same location. See You in My 19th Life is much more bubbly and the characters are younger than in Jirisan.
The ML and FL also share a somewhat mystical connection related to their pasts and coincidentally ML's sister. Both involve solving a crime (one about child abductor the other about a serial killer) which include the police force (both of which have cops that are slightly ridiculous and comedic). Both FLs struggle with memory loss and trying to get by in a world that they don't seem to fit into. Both FLs have loving single parent households, whereas the MLs don't have the support of family leading them to be alone, self-dependant and emotionally disconnected at the beginning. Both dramas have an enjoyable romance but also a dark crime investigation with different kinds of quirky comedic elements. Both are at times intense and thrilling that you can't stop watching. I would say Link: Eat, Kill, Love is more dark comedy and The Girl Who Sees Scents is more whimsical because, well, she can see scents.
Aside from sharing a major common song, though the plots are entirely different, the vibe is the same. One key component is the same: the guy needs to be committed and go through great lengths to convince the girl that he really does love her and isn’t chasing her due to limerence or temporary infatuation. Both female leads are afraid of getting betrayed by love and both male leads know their girls extremely well and are there for them when it’s most important.
