It's a masterpiece. Just pure perfection from its casts, cinematography, plot, storyline, ost and wardrobes. Tackling mental health in a spectacular way is very heartwarming and of course very timely during this time of pandemic. The relevance and moral lessons it implied can indeed touch the viewers' hearts. It's unforgettable. It will be forever engraved in the abyss of my heart. As of now, it's my number one kdrama, it's everything. Incomparable. THE BEST. Period.
