The production seems to be as bare-bones as they could come from the 2000s. A drama can still be functional even with the roughest cuts if other aspects held up which, unfortunately, isn't the case here. The writing was a big sloppy mess, incoherent, disconnected from reality and unbelievably corny, especially the older cast. The drama ended up with too many loose ends, these plot threads left untouched despite constantly building them up throughout the drama. For example, the story constantly hinted that Yoon Young and her husband were going to have marital problems and that was going to be their story but we never got to that point, making all the scenes including them leading up to that moment completely redundant. The writing definitely affected the cast's performance. You may have been excited to see the leads to be different from the typical young-blood dolled up faces but they don't bring much to this specific project, in fact, it's embarrassing to watch them here when you they're definitely more capable than that. They were in their 50s at the time but were acting like the typical shy 20s boy-girl for their romantic scenes. Speaking of cast members, I ALWAYS hated how Kim Hye Ok sounds when she screams or cries but this drama turned it up to 11. You may or may not develop tinnitus from the unbelievable intense screeching.
There was a transgender subplot and let's just say that the drama handled it as you would imagine Korean writers would do. The drama may seems promising from the surface but it's a big let down.
