The protagonist of the story is transported to another world, but another girl, (who I'll name B) who always causes trouble for the MC ends up following her to wreak more havoc in her life. When summoned, B can see the titles and names of those around them, but the main character cannot, so B takes advantage of the situation and proclaims she is the saint. The MC is cast aside from everything and, to ensure her lies don't get discovered, she makes sure that only she could use healing magic, and when the MC said she used it, she is thrown out of the castle, whereupon she heads to a monastery near the border where the war is being held. The carriage that she was in was attacked, she used the healing powers to stun the men attacking, which caused the guard to call her evil, stab her, and take some of her hair back as proof. The MC heals herself and gets ready to travel in the woods, when she meets an old man asking if she is OK.
The mangas is fairly new and only has one chapter out so far, but I can’t find it in my history or by looking it up.
