Armin Arlert x Kitsune!Reader: Deep in the Forest

All Hallow's Eve. An event celebrated by the 108th trainees squad to distract them from the horror of facing the titan's in the future. But what happens if Armin Arlert gets lost in the forest in the middle of the night on that day?( For a contest in deviantART. Forgive me if there are OOC characters TT_TT)
