Mushoku Tensei: A different path

Emotions fluctuating. New powers awakening. Bonds unstable. Mind distressed.
After the fight with Paul in Millishion, Rudeus takes a path different from what he should've gone through, changing his future for something that would make him go through changes never possible for him to perceive.
But the cost of such power was his usually rational thinking that turned into that of an actual child, causing him to question himself and his actions.
Beings besides Hitgami puppeteering and assisting him, closer to him than anyone knows, lurking in the shadows and watching him as they wait for their time to come.
How will he get his life back on track? What happens with the people closest to him? Will the powers he gained be worth it?
The slightest changes can cause disturbances to a story if even fate can't fix everything.
