This is a lighthearted and fluffy novel, but my only critique is that the ending felt quite abrupt. Many plot points, such as Ji Shihan's brother's transformation or the development between Ji Shihan and Wen Yue, were left unresolved. Ji Shihan's brother's character seemed like a potential antagonist, but his change was too sudden after a single punch. Wen Yue's introduction seemed solely to create tension between Shi Chen and his mother, and he disappeared shortly afterward without further exploration. There was potential for a deeper connection between Ji Shihan and Wen Yue, but it was completely overlooked.
Regarding the ending, the most significant point is Nan Xiao's arc. He was portrayed as persistent and unyielding, yet his storyline was abruptly cut off. I expected him to play a bigger role in disrupting the main characters' relationship, given his誓言 not to give up. However, the ending was rushed, leaving me unsatisfied. On the positive note, I'm glad that Shi Ning didn't end up with Nan Xiao, as it deviated from the typical romance trope.
Throughout the story, the focus on studying and romance was clear, and the title appropriately describes the主角 as a Mary Sue character. Everyone fell for her, and she effortlessly overcame challenges. While she was depicted as kind, wise, and innocent, it would have added more depth if there were more conflicts and internal struggles. Overall, it's an enjoyable read for passing the time, despite the lack of angst and depth in some areas.
