Haruto came to the college in the third week of September and reviewed the timetable and saw that the first class was the class which Sansui was in which is the turn of the events where Sansui will not expect and in fact will regret expressing his opinion towards him after he arrives.
In class, Haruto started taking attendance and as he read Sansui's name, he looked at Sansui's dead in the eye and said "heard you from the math professor, Let's see what you got..." in a condescending tone. At this point Sansui was confused of why he gave a death stare and Sansui replied "Sure then sir, I hope this is going to be a good year with you". Haruto clearly didn't like the response but decided to take the revenge plan gradually and calmed down and started teaching the class as normal, Haruto decided to ask the most difficult questions when the 1st part of the lesson ended 15 minutes before the class ended and when Haruto saw Sansui, he thought of a great opportunity to overthrow him and asked Sansui a question. Of course there is a drawback the fact that he knows the main subjects better than History in Social studies because in Social studies, the answer must be the exact statement mentioned in the textbook in order for an answer to be correct. Sansui usually understands and writes in his own way... But the fact he has to memorize the concepts by heart made him incompetent in that subject...Now Sansui told that he didn't know the answer to the question, in which Haruto replied "I don't even know how you managed to get to the most prestigious college without knowing this basic question and to top it all off you were given a scholarship, meet me after class" and he proceeded to ask the same question to Chifuyu and he said the right answer, then Haruto turned back to Sansui and said "Learn from him, even if he's your friend he has got a good influence unlike you" The bell rang and the teacher dismissed, leaving Sansui was stunned because he did not expect such kind of attitude from a teacher...
