Chaeyoung never expected a boy with sparkling eyes and a beautiful laugh to climb intoher window one night under the pseudonym of Haechan, but now, she cantimagine life without him. Foreword “Oh, Haechan isn’t my real name. It’s a sumo limb.”Chaeyoung started at the boy, confused. A sumo limb? What? “What the fuck is a sumo limb?”“You know, like a pen name?”“A sumo limb?” Donghyuck nodded quickly. “A sumo limb?" Again, he nodded. She was about to repeat her question, though suddenly, it all made sense to Chaeyoung. "Oh shit, wait! Do you mean a pseudonym?”Haechan paused. “The fuck is that?”“A pen name.” Chaeyoung said blankly. "The words not sumo limb. It’s  pseudonym.”Donghyuck looked mildly bewildered. “A pseudonym? Why would anyone create such a stupid word? It literally makes no sense, and I couldve sworn it was sumo limb.”Chaeyoung snorted to hide her laughter. “Sorry, but no. Its a pseudonym.”
