Both are inspiring. They work together and study hard and get their favourite University. Both have same school environment and it's very enjoying. If you love either of them then you will definitely like watching other one too.
I have watched don't disturb my study a year before watching our secret. These both have the spirit to work towards their goal.
Both the dramas are sweet. These both gives the same vibes .The situation of the male lead in their past is similar in both the dramas. While the difference is between the parents support.
These both dramas took my heart. This two are my favorite forever now. I will recommend these both. You will definitely like both.
