I'm sorry, I'm not familiar with 'kiraz mevsimi' specifically. It could be a very specific or regional story. Maybe it's about a cherry season ('kiraz' can mean cherry in some languages) in a particular place or a story with a character named Kiraz during a certain season.
The 'kiraz mevsimi' story remains a mystery to me. But if we break it down, it might be about a time - the season (mevsim), and something related to 'kiraz'. If it's a cultural story, it could be about the significance of a cherry - like product or a person named Kiraz during a certain time of the year. Maybe it has elements of celebration or hardship related to that specific season.
Well, one major difference could be the way the characters are drawn. In the manga, there might be more detail and specific styles that don't always translate exactly in the animation.
