Secret After Work

Présentation

Yokoya, a serious new teacher, and Seo, the laid-back school doctor, are bitter rivals. Yokoya can't stand Seo's inappropriate work attitude and how, despite it, Seo remains popular with the students. "I care about the students way more than he ever does!" Yokoya often tells himself. However, one evening, overwhelmed by the daily stress, Yokoya collapses while working overtime. To his surprise, it's Seo who comes to his rescue, providing first aid. Grateful, Yokoya thanks Seo for unexpectedly taking care of him. But before he knows it, Seo is carrying him... to a love hotel! (Source: Kadokawa, translated) Note: Includes one extra chapter.
