Bisang! Cheongchungirokbu

Cheong-Yeon is an academic legend with a soul of ice. To save his college applications from a failing character evaluation, he agrees to mentor Su-Han, the school’s most notorious troublemaker. Su-Han earns nothing but zeroes and lives with zero motivation. While Cheong-Yeon only wants his college recommendation, Su-Han just wants to be left alone. As they clash over study habits and life choices, the top student begins to find his missing empathy and emotions in the most unexpected place. (Source: Tappytoon) Note: Includes 15 extra chapters.
