I feel the story is getting bland slightly. I guess the original story is short and linear, whereas devs try to cram as many arts as possible to keep the game sexy. I suggest devs put some conflicts into the story. For example, MC gets pregnant and her mom strongly dismays the relationship between her daughter and the goblin, but the daughter refutes her mom with the mother's affair with the blacksmith. They finally decide to convince each other with "actions", not "words"( foursome swinging arts could be helpful). Or, devs can let the goblin be kidnapped by the human "hunters" or "guards", the four girls need to rescue it with their "skills". It is just my personal view, though. I enjoy the arts very much.
