### Summary
The chapter's central revelation—a strong implication that Woojin has cheated on Siyoung before—triggers an explosive reaction from readers. The comments are filled with shocked and furious repetitions of "Again?!", as the audience calls for retribution against the "scumbag" boyfriend for his repeated infidelity over a nine-year relationship. This new information solidifies Woojin's status as the villain, with readers noting his "dry" text messages as further proof of his lack of remorse and effort. In stark contrast, Jiho is celebrated as the "greenest flag," whose decade-long wait is seen as the ultimate proof of his devotion. Readers are eager for him to comfort Siyoung, believing his patience is about to be rewarded. However, the critical question of whether Jiho knew about Woojin's cheating lingers. While some maintain that his silence would be a betrayal, a prevailing theory suggests he knew but respected Siyoung's boundaries, letting her discover the truth herself. Amid the character analysis and emotional outrage, the series' "pretty" art style continues to receive praise, and the audience widely anticipates that the current events will finally push Siyoung and Jiho together.
