That blood might be from her trying to bite her nails but im guessing arth saw that and prevented her by doing that by replacing her nails with his arm, thats my theory also I think Sasha might die idk because the tag says tragedy but she's compatible with all three Rebecca, Naska, and Arth and I just don't see a happy ending for them, thats what I think so don't take it to heart lol
Shut up omggg don’t do this to me ╥﹏╥
