Secret After Work (NATSU Masaki)

Yokoya, an earnest new teacher, and Seo, a public health doctor, are bitter enemies. Yokoya doesn't like Seo's attitude toward work and his popularity with the students. (I definitely think more about the students than he does..!) However, when Yokoya collapses during overtime work due to the daily stress, it is Seo who comes to his rescue. He gives him first aid and is surprisingly grateful that Seo takes care of him, but the place Seo carries him to is a love hotel! A cynical infirmary teacher and a serious, stressful teacher in a bickering couple love story!
