this is my FIRST TIME WRITING a review

The thing about this drama that, at first it attracts a particular type of viewers (anyone who enjoys romantic, happy and funny stories) i definitely thought that its gonna be a romantic / sad and inspirational drama with a bit of science-fiction on it. but almost everything changes after the first episodes, and it becomes really sad and tragic in my opinion.
i had hope that things will be fixed within the episodes ( mostly between the two main actors that i personally want them to be together so bad LOL ) ...
