I finished seeing this drama, and I have to say I really enjoyed it. It is the story of a young lady who lost her mother in a fire when she was a child, but this event didn't ruin her life but instead motivated her to live a good life, try to find happiness, and be optimistic. This is the reason why she is chosen as a part-time employee, working for a wealthy family. The grandfather has three grandsons who, in spite of being good people, cannot seem to find a good path to build a normal family relationship. They bully and despise each other, so much so, that they didn't even dine together. Thus, our female character has different missions to fulfill, from finding a way for the family to take dinner together, to going on a trip, to going to a memorial, to save their grandfather's life. The only forbidden interaction is, of course, love and dating, which as you can assume happens. The girl falls in love with one of the boys and they gradually become very important to one another, convincing, in the end, the grandfather to accept them, in spite of the low economic condition of the female lead.
The drama is about loss and grievance, about finding the strength to get up and try to live your life as best as possible, about family values, about friendship and love, and about things in life that really matter. Each character has its own odyssey, with adventures and feelings, and discoveries of real life. Wonderful actors, story, music. I recommend this drama, wholeheartedly.
