It might be plain to see, but I see nothing set in stone yet. And even then, which girls precisely? I don't want a vague harem ending. I want a proper detailed, well-explored one. The series deserves that much. The mediocre open harem ending which tells the viewer "They all share the same love" and then fade into sunset is something I've seen aplenty. I need more than just reassurance in the parting words. I want to know whether it can work and last and that none of them will drop out as they grow older and that the MC can handle being the husband figure for all of them. Sure he doesn't need to do administrative work, but he is still the only "man" for them. But hypothetically if you consider the variables, then the girls might turn bi for when he is too busy or tired. Harem life is always interesting.

Nah. That last bit is covered if you recall that he is still a teenage kid. =P Other older characters had faced plenty of war and strife as well but they still had time for family even if it wasn't as much as it normally should be.
