This is not your average Korean drama feel good romance. The main leads are both traumatised and fragile, for numerous reasons surrounding their relationships in the past. The whole visual and audio vibe of the series is dark, foreboding and claustrophobic. The soundtrack is intense and overwordly, mirroring the plot. Numerous images have thematic relevance and bring a sense of unease. The acting is amazing with both characters being somewhat likeable once you get past their frosty and damaged exteriors. They bring much needed healing to each other. The mystery of the trunk brings things together at the end, but the true drama surrounds the nature of manipulation, trauma bonding and the importance of a sense of safety in relationships. The plot is a little unbelievable at times and sometimes the character motivations seem inconsistent, but the surreal nature of the show is such that you can gloss over these without much problem.
