Overview

The "Gear" is the symbol of the Faculty of Engineering. It's part of a system of cogwheels which power and run a device. If one gear fails, the device stops working. In order to get this gear, all engineering freshmen must first undergo the SOTUS (Seniority, Order, Tradition, Unity, and Spirit) system. Third year senior student, Arthit is the head hazer who leads the hazing team in disciplining the freshmen students by following the code of the SOTUS system. His methods were misunderstood by the students as a form of abusing his power as head hazer when in fact all he wanted is for the freshmen to get to know their seniors, rely on them when they need to and vice versa. Arthit was seemingly unstoppable, until Kongphop stood up against him. This initially resulted in a strained relationship between Kongphop and Arthit. However, continuous encounters between the two helped transform their relationship into something much more affectionate.
