Introverted Boss. I really think the drama portrayed mental ilness in a very realistic and good way - which I have discovered is a rarity in korean dramas. I don't want to spoil too much but I think they portrayed the loneliness of someone who is depressed very well, and how it affects the people around them. For example: Sometimes there isn't any signs at all, and there was nothing you could do from the very beginning. I don't know how to explain it. I just really liked the drama. I could really relate to the mental illness aspects and I cried a lot, in a good way (I hate sad dramas usually btw haha). The romance was quite good as well!
