Just let me guess:
1. The old man survived;
2. He will capture, at least, the girl;
3. The girl will be raped by the crazy lesbian we saw few chapters ago while the MC fight (and kill) the old man;
4. MC saves(?) the girl and even help her kill the lesbian (Unless the author wants to show how edge he is by killing another female character close to the MC... again)
5. (Maybe?) Another "mid-boss" shows up before the MC faces the final bastard while somehow another girl "close" to the MC shows up in this mess. Rinse and repeat.
Anyway, I'm just here to see how it ends (soon, I hope).
