No ? "End goal" is litteraly what it mean. By the end on the story, MC will "settle" with one of his love interest. But while it's still ongoing, MC will just make more & more love interest (meaning character that fall for him) even if himself isn't that interested. If you need an analogy, it's like the typical love triangle on steroid. It's how most of "reverse harem" are handle (FL with multiple love interest).
It isn't the sole way to depict a harem of course expecialy when it's a Harem with a ML with multiple FL. Some will really never settle and drag forever (typicaly when the romance is more of a subplot, for fanservice in a shonen for exemple) or some more extreme will go with MC actually have multiple partner for a more... "mature" content.

Well, one is definetely favored to be the end game but to be honest, this story isn't heavy on the romance. It's more about a group of trainee trying to debut into Idols together while solving each of their own struggles & dramas along the journey (making them falling for MC by doing so). It was the focus of MC so far.
Can someone tell me is this harem or not? Or there is a specific ML but the other still love MC
