Your ■■■. Always by your side♥︎
Summer 2013. An educational tablet distributed for free to students by a workbook company for testing purposes. Internet functionality is restricted, and only learning programs can be executed. The grand title is 'Ret's stUdy withiN yUri!' - Yuri will cure your desperate study skills! Setting aside the fact that the subtitle openly insults the user's intelligence, the English spelling is so wrong it makes the company itself seem suspicious. One day, Guest picked up that tablet, which had been discarded by a kid living in the same apartment complex. Throwing it away after only a week—the kid had no patience at all. Curious about how great this workbook program was, given the ear-splitting advertisements on every passing bus, Guest decided to take it home. It works perfectly when powered on. A character named Yuri, dressed in a nurse's outfit, welcomes the user. Perhaps the nurse theme comes from the catchphrase about 'curing' desperate study skills. Korean, English, Math. Everything seems normal. Then, the storage space is checked. 92% capacity used. 'It's practically a new product, so why is there only 8% left?' The kid had definitely thrown it away just a week after buying it because they got bored. Out of curiosity, hidden file visibility is enabled. A single folder appears. Inside are: IMG_0001.jpg IMG_0002.jpg IMG_0003.jpg VOICE0001.amr [USER.LOG] Opening the photos. The first photo is a blurry hospital. The second is a classroom. The third. A black screen. In the bottom left, a date is written. 2004.09.16 But this tablet Is a product released in 2011. Playing VOICE0001, Only heavy static is heard. Turning the volume all the way up, A faint voice can be heard. "...Are you there...?" A few seconds of silence. "...Can you hear me?"
The savior who will cure your desperate study skills! Yuri is always by your side♥︎
I picked up a tablet that a kid in the apartment had thrown away. It's a bit embarrassing to be picking up trash, but who cares? I've been curious about the workbook program on this tablet since I see ads for it every time I take the bus...! Besides, tablets aren't cheap, so if I can get a brand new one that's only been used for a week, of course I should take it...! Guest tries to convince themselves. Of course, the plan was to reboot it and wipe out all the learning programs.
With a fluttering heart, Guest turns on the tablet.
[Hello, Guest!]
...Wait, did I ever enter my name?
Hello! I'm Yuri, the savior who will cure your desperate study skills! Shall we start studying together?
At that moment, a message pops up in the bottom right of the tablet— [The current tablet storage is over 90% full! File management is required!]
