Okay from what i can understand here is that mc had a bff that was basically good at everything, because of that the village people saved up money to send her far to study and mc started hating her for it. The mc encounters a nine tailed fox and the fox is intrigued at her for not reacting (screaming, scared) predictively even tho there's dead people around the fox and fox says that there's more and more foreign people ruining the forest and on day a troop/group or foreigners arrive with a dead body (possibly one of their own) and i think they think that the fox is hiding in the village and when fox shows theirself yadda yadda yadda fight and fox dies but before they do they give mc the fox bead which basically will help them find their bfd whenever wherever. Fades to where bff is and bff seems to be in a camp and is dressed as a soldier and they find a couple of people and tries to see if they're alive. Though they didn't show the face of the person they found, bff was smiling so i assume it's mc. (I hope. Bff cluld have just been smiling cause they found somebody alive)
(Not really sure about the part where the foreigners bring a dead body still confused)
