Nukoduke has moved to マンガPark (Manga-Park – https://manga-park.com/title/52).
To read, you’ll have to buy coins or you can install the smartphone app which will let you read a number of chapters for free a day.
They’ve uploaded the chapters originally serialised in the Hana to Yume magazine so the numbering is different now (It’s following the book numbering). Chapters 105-107 will correspond to chapters 196-198. From chapter 200 onwards (since chapter 108/199 released on HanaLala Online) I will start using the new numbering and slowly re-number the past chapters. We will also be slowly working on those additional chapters.
