First loves were supposed to be great, right? But hers just ended in a messy disaster. And it was all because of that one guy. Luna: "Juan Miguel Antonio Laxamana. I will never forgive you." Juan Miguel Antonio Laxamana : "...I'll just ask you again. Kapag nasa tamang wisyo ka na."

The new semester opens with a bang that shocks the four Houses of QED University, an exclusive school for promising students of the science of deduction and art of detection. The Holmesian Harriet Harrison never thought that the day would come when their archnemesis Moriartian faction beat them in the House War. Her competitive attitude toward her class rival Morrie Moreno intensifies, each trying to outsmart and outmaneuver the other. But trouble does not stop there. The most charming Adlerian Aiden Alterra commits himself to a "secret mission" and starts pestering Harriet. The seemingly mute Wilhelmina Williams from the Watsonian faction also gets dragged along with the three in a string of mysterious incidents that will plague the university. Despite their dissenting motivations and unique personalities, the four will have no choice but to work together as a team toward one common goal and against one common enemy. The classes begin.
