Sotus: The Series (REWRITTEN.)

There's a university system called SOTUS (a tradition in which upperclassmen 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
