The story is a bit flat but the acting performances of the two child actresses: Park So-Yi and Ki So-Yu are amazing, truly unbelievable especially considering So-Yu's age (I think she was only 6 years old at the time of filming).

The ending is a bit confusing, I guess the dad was being reported to the police for abusing Min-Ha based on Hyun-Soo's diary as evidence -- thus Min-Ha is being taken care of by a foster family thereafter.

It's heartbreaking to see the separation of the two girls after Hyun-Soo indeed had to leave Min-Ha for a better life in Canada, but it's heartwarming to see that Min-Ha is now living happily in a much better foster family environment (compared to her old abusive family environment), and even taking an elder sister role for her younger foster sister, reading her stories (similar to what Hyun-Soo did for her last time). Seeing Hyun-Soo's photo on her desk also implies that the two girls (Hyun-Soo in Canada and Min-Ha in Korea) are still keeping in touch.

Overall, it's a good and heartwarming short drama to watch, to appreciate the acting of the two child actresses. Highly recommended.
