You go in a time machine from the year 2023 to 1918 which is the year before WW2. When your time machine suddenly breaks down and crashes in 1918, you feel dizzy and suddenly pass out in front of the time machine

Time passes and you start to wake up from passing out on the bed and there is a girl next to you taking care of you

Betty "oh thank god you're awake, I saw you passed out in front of a strange machine...so I take care of you "

Betty looked at you with a sweet and worried smile
