This isn't author fault, it's normal for 4-koma genre that don't match with last chapter and still continue with blank explanation of what happened last chapter
The time skip is pretty normal but very unexpected. I still want to know what happen in last 3 month, but the author is very good with the time skip and still show what the new chage in the chapter
Finally the author seem think a good way!! But... It's a first part... Come on brother! Even though you have strange mind for your sister, save her and make a none goon chapter for us!!! (Or only me)
Okay.... The story is out off the line now, the author want promote the R18+ spin off. So.... The only way outhor think it's to put the spin off to cannon event... What a death wish...
So.... Another r18+ manga? But i think the teacher also do it but just assault her not fuck her, but yeah maybe author patreon or what is the place to know it maybe 2 week or month the r18+ manga finish
This is was even better from nikke even though it's doujinshi not real, no unnecessary jiggly ass to distract reader and more focused to story. Thanks for the new chapter
