Ex Gon

There are lots of lapses like how it came to that every turning point and how did every characters involved with the leads, also it only shows Takaki's story. I decided to watch this out of curiosity, and I'd like to ask if where can I read the whole story. I got a lot of questions and I think I need the book or link to make my mind clear 😬

I love the story but I don't like the way it ends. Why does the one who caused the stir of these teenagers got her happy ending? These students suffered more than she did in the past. They ended up broken. I don't get it! I WANT SEASON 2 for Hanabi and Mugi 🥺💔
