I enjoyed this drama on a more profound level than I thought I would. I loved the narrative.  I actually looked forward to every episode to see how the characters would resolve their differences and agree to accept each other instead of trying to change each other.  I particularly relate to how the female lead went through doubts about whether what they had was acceptable to her. I admired the male lead for being so sure of what he wants and going for it. The title of the drama is temperature of love so it would not be right to just expect love at it's most passionate and when it is at it's most frigid.  They had to explore the many "temperatures" that a person has to go through in a relationship.  Love is different for different people and they express it differently, they go through it differently , they have different perspectives, and different expectations.  As a persons who has experienced a few serious relationships, I can understand how there is not one way of experiencing love and attaining its essence.
The acting was commendable and the chemistry between the leads was palpable.  The second lead had just as good a chemistry with the female lead and the love between the men.....enviable.  I also  enjoyed the side stories of the asst. writer and director -cute  and immature, but these types happen in real life.  The sous chef and the other writer,  to me, showed growth in their relationship.  The parents are realistic in that there really are parents who act more childlike than their children, more dependent, more insecure, more afraid.
Yes there were parts that others will see as boring but it's how life is.  There are times when you are searching for direction and nothing much seems to be happening.  I guess i didn't get bored because I felt like I saw fragment of my reality in this drama. I will watch it again someday to savor the experience of the different temperatures of love.
