I don’t want to be mean but I doubt that people in general like that Hana girl. We don’t really care about her and she’s boring; we read a KnB fanfic to see the character interact in different ways, not some random no-name girl without personalit.y
i had to force myself from stopping with reading, i did not like this chapter. especially the interactions with those sisters (mostly skipped through all the dialogue so i don't remember the names)
The romance is fine but you should decrease it and focus more on the KnB characters because we came here for them and MC still haven't fully exposed all of his skill/weapons
