Why is my time traveling to the second dimension such a weird rule story?

Traveling through the second dimension, both parents are dead, and there is money and a house. Although there can be no sister due to the rules of the cat guest, this is definitely the direction of the protagonist of the daily harem in the second dimension. I guess the next step is to flatter the house and be surrounded by girls, right? [Welcome to the "Sacrifice Game", I wish you can witness the end in real fear] Wait, this script is wrong, right? Corpses are whispering, caves are crawling, paper people are asking for directions, ghost villages are wandering at night, and pupils are peeping under the bed... The weird rules weave blood and cannot be escaped. The only way is to face the endless nightmare and seek a glimmer of life. So being entangled by these horrors, can you give me a system, the best kind of sign-in is awesome! When thinking about this, I found that I got the ability to replay after death. It is indeed a plug-in, but doesn't this mean that I have to keep trying and making mistakes with my life? I don't want it, I don't want to be a protagonist like 486! Who will save me! Then he turned around and saw the girls trapped behind him, including Kaguya Shinomiya, Chika Fujiwara, Ichiri Goto, Miko Yotsuya, etc. Damn it, come on! How can I let a beautiful girl sacrifice herself in such a place? I want to create a happy world without Kyon and Kaba-san!
