Traveling Through a Parallel World and Being Targeted by Roommates

[The sensitive little pitiful person is attacked by the X yandere sliced personality] [*Two male protagonists*Team pet*1v1*with tentacles] Because Xue Xingju is an orphan and has no one to love her, she is a very introverted and sensitive little transparent person who has a lot of inner drama and longs for the care of others. Suddenly one day, he came to the space outside the world. There was a "Xue Xingju" who looked exactly like him, saying that he came from a parallel world, suffered from a serious disease, and wanted to change identities with him. As soon as he opened his eyes, Xue Xingju was already in the new world. He was still at university in City S, but his roommates had changed. The three roommates have different personalities. They often stick to him, bring him food, wash clothes, and even want to... Annoy him. Xue Xingju didn't feel anything was wrong at all. As a transparent person, he was very happy to finally have someone to accompany him, but he didn't know that the tentacles behind the three roommates behind him looked ferocious in the night... He knew from the beginning that "Xue Xingju" in his world had changed his chip, and the smell became full of orange fragrance, which always surrounded him. He was curious and fell in. Since ancient times, no one can see him, let alone know his appearance, or be liked by him. His paranoia and madness do not allow anyone except him to get close to Xue Xingju, and no one can covet his lover...
