There's a university system called SOTUS (an acronym which stands for Seniority, Order, Tradition, Unity and Spirit - a tradition in which upper classmen sometimes exploit and even abuse freshmen and others seeking acceptance). Junior level students are required to mentor those freshmen and be respected in return. Enter a rather assertive and vocal freshy at the Engineering faculty named Kongpob who gets to be under the mentorship of Artit, a strict Junior who happens to be the boss of his year. ~ Based on a BL novel by BitterSweet (Nabu Publishing) Watch drama online for free.
