Yes. What is in the game right now is the prologue, it's the introduction to everything. The Chapter 1 will be all about training and the MCs' relationship with themselves. As a player, the player is not forced to send the girls to work, you can fish or mine to get money.
The next update reinforces this. You can send girls to work or just do activities like fishing, foraging, or mining with every one of them, boosting a little affection.
The MC will improve and fight, but right now he's just a fetus trying and pretending to be a Hero xD
