It's about a self-insert who gets isekai'd into the game "Little Goodie Two Shoes". He's in his room on his computer attempting to get all 10 endings but then lightning strikes his house and he gets sucked into the computer. Or a suspicious pop up appears asking if he wants to be in the game, he clicks yes then he gets sucked into the computer. He simps to Elise.

After getting sucked into the computer he finds himself in this.

With options on what abilities to choose from to he can survive and defend himself without getting killed off easily. He scrolls through which abilities from different anime and video games to choose from. Personally I would go with using all elements, Shirou Emiya's powers/Archer's powers, and Tsuyoshi Mukouda's online shopping ability. And a magic door that can be placed on a wall and leads to a bedroom inside a small reality marble  with a house and landscape the self-insert can make into what ever he likes. After he's chosen his abilities his currency is randomly generated right in between poor and rich. Then he's choosing which clothing to wear so he does not stand out. After that he is teleported to the world of "Little Goodie Two Shoes". All he has to do is win Elise's heart and make it to a happy ending.

He gets teleported to the outskirts of Kieferberg during the morning day time. He is in the role of a traveler. He enters into town. Later on Elise runs into him at the water fountain.

When night comes, he secretly follows Elise. I'd want the self-insert to be staying with Elise. When her lamp goes out, the self-insert uses his fire magic and lights up the area. Then he bribes  Elise to let him stay with her. At the part where Elise is attacked by the vines and braanches appearing, the self-insert rushes in and slashes the vines with swords he projected. Feeling terrified, Elise embraces him and says that he can stay with her. Then after he says a few words, Elise realizes then she instantly let's go of him and acts all Tsundere on him. On the Sunday morning, the self-insert goes to the church with Elise. He also helps her work for money by helping her with her jobs/chores the villagers give her.

When going into the woodlands/the dungeons at night, the self-insert protects her with his anime powers. He has his chance with helping Elise avoid a bad ending to get to a happy ending and winning Elise's heart.

It ends with the self-insert marrying Elise then having a family with her. By the way, I haven't played or seen any keys plays of the original game, Pocket Mirror since Little Goodie Two Shoes does take place before Pocket Mirror.

And that was another idea. I honestly hope that someone makes a Little Goodie Two Shoes x male reader FanFiction someday.
