Even though they were in different majors shinchan and kazama often met each other.....kazama had got used to shinchan a lot.....to a limit that when he didn't see him his day went gloomy....He had not realised that he had feelings for shinchan.....shinchan on the other hand was carefree. He was oblivious of kazama's feelings. He didn't know that his actions were impacting kazama in a loving way.....With such relationship they had come to where they are today.....but things weren't the same as back then.....With time they were getting more and more burdened for their future and their studies.....which resulted in them focusing on their studies....even after such condition both shinchan and kazama stayed the same maintaing both work life and friendly life.....
They spent their time studying and it was finally their last year...after that they'll be pursuing their careers....kazama had got quite the hang of his feeling for shinchan as he realised he couldn't spend a day without him....shinchan as playful as always flirted with kazama and all the pretty ladies out there ....which sometimes bugged kazama.....he didn't know why he was feeling that way....
