First love/Innocent/Pure love

Hello Guys! 

Can you guys recommend me a drama that shows Innocent/Pure love like Koizora, Chugakusei Nikki,  Love and Fortune, Tree of Heaven. I know that some of the dramas that I listed are "taboo" but the thing that I like the most about them is the pure love that they show and their willingness to fight for their love. I hope you can recommend me some dramas with a similar theme. Thanks in advance!
