The story tells how Ye An An accidentally gets into Math major having no base in it. On the first day she challenges the top student of her class claiming she can catch upto her. But studying seems harder than challenging. Trying to cope up with studies she becomes frustrated and prays that a spirit or God of math might help her. The spirit of Math, Shu Xue comes to her rescue and makes her go through difficult tutoring. An An tries to escape this training several times but ends in despair. While tutoring they fall for each other. Completing his target, could Shu Xue stay by An An's side?
This is one of the typical cold male lead and bubbly female lead stories. The plot wasn't that interesting. A lot of things seemed unclear.
As this is a short web drama a few things are ignorable. It had 18 episodes each having 10-11 minutes. So for me it was one of those dramas you could watch once but not worth rewatching.

Interesting fact: The ML's name Shu Xue is similar to 数学 (shùxué) meaning Math in Chinese.
