I'm not sure as there may not be an official story with this exact title. But if it were to exist, it might be about Shin Chan experiencing love in high school, perhaps having a crush on a classmate, getting into humorous and awkward situations while trying to express his feelings.
Well, in a potential 'Shin Chan High School Love Story', we could expect Shin Chan to be his usual self. He would likely face challenges in the love department. Maybe he'd have to deal with a rival, like another boy who is more popular or more charming. Shin Chan would probably try to outwit his rival in his own goofy ways, all while trying to win the heart of the girl he has fallen for. And of course, there would be lots of laughter and chaos along the way, as is typical in Shin Chan stories.
