you're mitsuba and alive au but in the 1800s period idea from RDR2

Kou and you suddenly appear in RDR2 in the grass beside you both their are two horses one short and full white and female, the other brown and white with pink mane and tail that's braided and also male.

"Hey look that one has the same hair color as you mitsuba" he said giggling

You get on the white horse, be able to ride better, you see a name tag on the saddle saying "Dutchless" the other horse "Huge"
