Honeymoon Salad, Umi no Misaki Recommendations
Both manga involve a guy trying to sort out his romantic feelings for multiple women at the same time. In both cases, a harem develops around the male lead, but without all of the usual "harem antics". Instead, the focus of each is on how the man comes to know--and love--the women around him, and why they love him back in turn. The difference is that UmN is more of a slice-of-life and has a mystical quality to it, where Honeymoon Salad is much more grounded in the doldrums and drama of real life.
