First-year students draw lots to determine their peer mentors and, by a stroke of fate, Arm lands himself in the exclusive circle of “Perfect 10 Liners,” a group comprising extraordinary students from various years, with Yeepun as his second-year peer mentor. Yeepun entrusts him with the formidable task of managing the Engineer Cute Boy page, a widely popular online platform. Despite his reluctance, Arm performs admirably as the page’s administrator. In response to many fan requests, he uploads a photo of third-year civil engineering student Arc, unaware of the prohibition against doing so. Not knowing the admin’s identity, Arc sends a harsh message demanding the photo’s deletion. Detesting Arc’s rudeness, he develops a dislike for Arc before learning that Arc is his third-year mentor. Despite his reservations, Arm finds himself interacting with Arc with some frequency, for mentorship and otherwise. What Arm doesn’t know is that he’s been let into Arc’s inner circle because Arc was smitten with him at first sight. On his first day of university, disaster strikes Gun hard. Hapless as he is, Gun manages to break a bathroom faucet. Fortunately, a classmate comes to his rescue. Amidst the chaos, however, Gun doesn’t get a look at his saviour’s face, just catching a glimpse of their shoes. Eventually, he tracks the shoes to Faifa and expresses his gratitude. As they get to know each other, Gun realises it was actually Yotha, Faifa’s older Irish twin who he should be thanking. Gun can’t sleep in the dark due to an unfortunate childhood incident. This is a problem for his roommate who can’t tolerate sleeping with the lights on. Yotha, however, has no such issue and offers to switch places with Gun’s roommate as he rarely returns to the dorm at night. Yotha keeps his promise, disappearing after dark and returning in the morning. Wine becomes the latest member of the Perfect 10 Liners through the lucky draw. His second-year mentor is preoccupied with his boyfriend, leaving him with little time for his mentee. Stepping in, friendly Faifa takes over the role and looks after his older brother’s mentee. Faifa learns that Wine recently ended things with Toey, his girlfriend before university, after developing feelings for her older brother Tor. Now that Tor has come out as attracted to men, Wine is hopeful but unsure about approaching him. Faifa volunteers to serve as Wine’s practice ground, allowing Wine to hone his approach before making his move on Tor.
