Did I enjoy watching this drama? No. A big no.
Did I finish it no matter what? Yes.
It was a heavy load on my shoulders which I am still feeling. Wasnt enjoyable for me at all except few scenes. Why? Cuz it was so relatable for me. Relatable much as giving pain to me. Some fears mentioned were my own fears that I am afraid to mention. Some frustrations were my own frustrations that I can't find any way out. Some weariness was my own weariness that I am struggling with for many years. This drama didn't do any good to me. At the beginning of the drama, we were all sad. All characters and me. And at the end, at least some of them are happy compared to the beginning, I am still sad. Nor their sadness neither their happiness made me happy.
I can see that why many people like this drama that much. It is in a different league compared to most of the dramas. But I prefer dramas with lower quality and higher pleasing level.
According to me who can enjoy this drama most? Adults who are satisfied with their lifes. They might have problems in their past, but now they should be happy about their life in general. I think for younger people like teenagers, it can be a boring drama with 'pessimistic adults', it can be seen as "unrealistically plaintive" even if it is totally real. And I think for the adults like me, adults who have big problems, who have big disappointments, who have to deal with things that they've never thought they are gonna deal with before, this drama is heavy load. I am happy to finish this drama finally. I would never start it at the beginning if i've known it is something like this.
