Survival in the second dimension, bringing a girl and being watched by barrage

Time travel is an immoral thing.
At least for Dongyun, time travel is a very immoral thing.
If he traveled to the world of Oregairu, the passerby heroine, the pig-headed senior, no, the blue pig, he could accept it.
But what the hell is this, traveling to an isolated island with no survival tools, no water, no food, and even no clothes, and still being surrounded by barrages of comments?
He was pessimistic about the future, until his real golden finger arrived, a useless angel fell from the sky, and a wild Kirby girl appeared from the grass (no, a hedgehog cat?), and he became even more pessimistic.
One monk carried water to drink, two monks carried water to drink, and three monks had no water to drink.
This cat can't survive at all!
