Neil was the only support role in the party. Because he handled healing, carrying luggage, support magic, and various other tasks all by himself, he made a mistake due to overwork.
That night, he was subjected to what was more like a reprimand than questioning, where any response other than "It's because I wasn't careful enough" wasn't allowed.
"Hey, why don't you just quit being an adventurer and go back to the countryside?"
In the middle of the scolding, the leader said that to him, and Neil finally snapped.
"Oh, is that okay? Then I'm leaving."
Having done more than enough work for two people, Neil left the party without hesitation and decided to return to the countryside.
Switching from a support role that didn't suit him to a solo mage, he leisurely headed for his hometown. However, after helping a village being attacked by monsters on his way back, his surroundings would begin to change rapidly.
