This is a time loop manga where the Cafe is stuck in a cycle. Hayato's grandmother was the winner of her harem which meant she left the harem for the next cycle, which is now. The cycle demands a harem ending that has yet to come so each winner can't be in the next. But the Black Saints are an unforseen circumstance which has many past winners return to the harem. The cycle has gone on long enough that it thinks it accumulated enough past winners for the tables to turn and a harem is inevitable. Hayato will correct the mistakes of his ancestors and accept everyone. This is how his grandmother returns to be his daughter too, because the cycle finally achieves it's harem and doesn't stop removing singular winning girls that want a harem ending.

Hayato's daughter will have many half-siblings.

Probably how this manga ends. It's been my fav for years but I just know I will hate the ending to the extent where I will delete all the chapters, fanart, and screenshots from my computer and put it on my 4chan filters.
