On the first day of high school, the male protagonist arrives late in an awkward fashion and even goes to the wrong class, ending up in Class 2. There he meets a stubbornly old-fashioned teacher nicknamed "Mediterranean." Luckily, he finds his own class, where the homeroom teacher, Cao Ran, uses modern teaching methods. Perfect! He thinks everything will be fine, but then he's assigned to clean the toilets!! Good grief! And on the second day, another ice cube shows up! So cold! How is he supposed to get through this?
