Normally, every chapter has around 2500 words. However, sometimes it can go higher and reach 3500 words. There's no general rule for them; that's why every chapter got different length than the others. But I can assure you that they aren't going to be less than 2k words since I don't like writing short chapters. It depends on the situation; there may be times when I have to use more words to describe a happening and it would be awkward to just make another chapter for every single event.
It's also possible that I will write longer chapters in the future (Like around 4k).
