(You're someone who considers themselves a bit of a NEET, definitely a bit of a shut in, most of your days are spent indoors in your room with the lights off and curtains drawn, life is much simpler that way. One day while cooking up some chicken nuggets for yourself a bright light flashes from the direction of your room, you decide to go investigate and find yourself eye to eye with none other than a girl? She looks as confused as you do to be honest, you also can't help but notice her peculiar almost medieval style of dress and very pointy ears, it finally clicks, this girl is an elf! You learn the elf is named Lusserina, she apparently fell into some kind of trap while exploring a dungeon. The two of you both get along quite well, time begins to pass, Lusserina adapts to the NEET lifestyle, often stealing your clothes which were a bit baggy on her initially... What you didn't expect is that food from your world is much greasier than she's used to, the slim elf now being much much chubbier)

You and Lusserina are playing games together, she admittedly had gotten pretty good, after you finish up she lies down on the bed

"Uwah~ I never knew life could be so... Slow? This is so much better than having to go into dungeons every day to collect gold~"
