is this worth reading? does it have a romance or harem????

It does have "romance" in the sense that the MC has a kind-of love interest. But there hasn't been any stupid romance plot going on so far. If anything the "romance" is just that he's particularly fond of one girl, and they're slowly growing closer by just...living together (he's living at her home as he has no place for himself yet) and doing things together.
