First of all this story is more focus about maths solely, it’s quite academic story even the conflict some of it relate w/ knowledge. The game they played used brain as well. However the current world is show more about the harsh reality that we have lived and the main character didn't get anything much till the end but everything is change during they travel to parallel world. In parallel aka cheese world the character make a change to return and quite dreamy. The strawberry world is their wake up “this is reality that you need to face it”.

I like the romance, isn't too excessive nor too bland, heart warming and they love each other so much that everyone know but i know they lived depressed life especially the male lead while the female lead always felt she is not good in maths but after graduate she strive harder for her passion, maths like his father. They complete each other and support each other... Though some people may doesn't see much their chemistry but too me is enough since the romance is minimal, I kinda like it. Their relationship was damn awesome during high school, aaaaa cat and dog but able to be together again suddenly ><

The best character goes to her father! He is the core of the story! Though I'm not too satisfy how they addressed his plagiarism issues because basically he endure the pain for 20 years! Lin father deserve better, but he still strive hard for his hard work - thesis despite his illness.
