Ch.9 reminds me of another manga. Can't put my finger on it but I remember that there's a manga with characters that are almost the same as those. Something about the long hair being a slave and being rescued by mL and then living with him for many years and that ML gave him his name.
They are milking this serie to much. It was good at the beginning but the more chapters there are the more boring it gets (〜 ̄△ ̄)〜
the paying readers want more, if you think the author is milking it yeah they are, because theyre literally getting paid to milk it
