Good manga. Had a bit of a serious psychological edge to it, with the threat of choosing a girl basically spelling the death for the third girl that everyone loved, who couldn't ever be realistically chosen, creating some understandable stakes for the characters to try and hide their feelings. Most of the characters are pretty mature and level-headed and end up rationally figuring things out, so even in a comedy of misunderstandings, most of it is due to their own emotional pains and denials (like tarou being in denial about various things, etc) and not due to some villain character. It also doesn't go too far into delving into some kind of anti-waifu rants or making it an otaku reform story, which wouldn't really have fit the mood.
The worst part about it was the fakeout cliffhangers...but it's a shounen romcom after all. It did manage to make constant slow progress with new revelations of sharing of info. Each "matchmaking" romance story arc were pretty good in their own right, exploring different aspects of love gone right/wrong, and it also never got too bogged down with introducing constant new main characters and sidelining the main duo/trio, and avoided haremization. The mangaka was also very good at drawing hundreds of different themed outfits for the ghosts to wear!
