It's pretty average. I enjoyed it, but it was pretty predictable and did nothing exceptional.
A lot of character traits were brought up but made to be completely meaningless (i.e. Shik-nam's love for math), and really caused the story to feel hollow.
I might be a bit biased too, because from the art and description, I was expecting a rom-com between two socially inept (in their own way) people becoming closer through their interactions. I.e. Shik-nam being a lot more obsessed with math, to the point it's an actual part of his character, instead of something said in passing. And for Yegrinna to be a social butterfly but lacking common sense.
But instead it's an feel-good predictable plot that had 2.5 dimensional characters, fairly lackluster character interactions, poor character growth, and a fairly disappointing ending.
