This story really moved me.
I have seen tons of cdramas and categorize them by: 1. Do not pass first episode 2. Good enough to watch at least half but eventually drop them 3. Watch until the end but skipping parts 4. Watch until the end really hooked and rewatch favorite scenes.
This one fall definitively in the last category.
I could relate with the characters . Love that they have flaws and their own emotional handicaps and limitations. Their chemistry is great.
The love story is engaging and even if you have some drama (that I usually hate) it's very well managed as not to be oppressive.
Also has its flaws and sometimes you get irritated by some behaviors but I found them believable ( yes sometimes you just can't move on and do stupid things).
Nice beginning and ending (ends well so it's worth the wait).
It's has been a wile since I enjoyed a cdrama this much :)
