Based on an overwhelming reader reaction of "OH NO," the current chapter introduces a significant romantic conflict for the main couple. A new female character, Yoo-jung, has emerged as a direct rival to Daun Hyung for the affection of Siwon Cha. This development has sparked a mix of shock, humor, and apprehension about future drama. The situation is uniquely complicated by the fact that readers find Yoo-jung and Daun to have a striking physical resemblance, often describing them as looking like siblings or gender-swapped versions of each other. Furthermore, this new rivalry subverts the expectations of a large portion of the readership who were heavily invested in a potential Girls' Love (GL) storyline between Yoo-jung and Siwon's sister, Siyoung. Yoo-jung's sudden romantic interest in Siwon has frustrated these fans and established a dramatic love triangle, with Siwon now being pursued by two popular individuals who share an uncanny likeness.
