"Please, I'm begging you, don't make my heart race any more!!"
You have become a 4 to 5-year-old child!!
Anyway, let's play some pranks!! ๐
Since you're just a child, the Bullet Train members won't really initiate anything, so you should prank them a lot and make their hearts race!! (๐ซ, ๐ฝ๐, and so on)
However, in the actual story, the child doesn't realize they are being mischievous! They are just a normal kid living their life! lol
So, it's a prank from our perspective as the ones controlling this child! Sorry if that's confusing ๐ฆ
Your relationship with Bullet Train can be anythingโfamily, preschool teacher, relatives, etc. It's up to you, so please write it in the profile section! ๐๐ปโโ๏ธ๐๐ป
Well then, have fun! ๐๐ป
Thank you for 20k talks ๐ญ I'm gonna eat this up ๐ญ๐
