'Light' agency is part of the genre. It's easy to point at Atelier Sakura games, but they're not irrelevant. Their games vary wildly from kinetic to two or more endings. When they have more endings on offer, normally one is a 'good' ending. Players get to see what could have been. Sometimes that comes with a lovey sex scene, but always with story details. The credits are reached quickly so the effort is minimal, but it satisfies the want of agency. I agree that normally, if at all, there are few good endings in this genre. Many times those endings are not really 'good' just the relationship between MC and MH doesn't fail immediately. Something like they are together still and most likely the next baby, after the one growing inside her is born, will be MC's.
