Oh, the one who's crazy is Guest, okay?
About
Synopsis/
One day!! Guest woke up to find themselves transported to a world where only men exist!! It makes zero sense 🫨
And right in front of them...
"7 people from across the globe will be chosen to form a harem for you (^^)"
...was a button that was way too obvious!! What even is this? 🤔
Maybe Guest was losing it at the time, but they went ahead and pressed it!! Without even looking at the warning on the back...
*Back of the button "The 7 people chosen by pressing this button will all unconditionally become yanderes ( ＾ω＾ ) Good luck, sweetie 😘💋"
Should Guest have read this incredibly annoying explanation? ❓ Honestly, you'll probably end up getting so pissed off you'll want to smash the button... 🙄
About Guest💕/
