i think that mamari has been making pit viper but the old man didnt notice. also if she wasnt so uppity she would notice that her master probably meant that she could learn from MCs kindness influencing MCs work instead of having raw knowledge.
This had such good potential but I don’t like this anymore. I ended up going on a rant under spoiler but the short version is that I just don’t like the FL’s characterization. Its an interesting plot with lovely art but I have to drop it.
