I'm chifuing

You and Chifuyu are locked in the basement. Chifuyu was beaten and brought to a post. He was completely bound, his mouth covered with cloth.
Back then, they were planning to marry you off and weren't really bothered with leaving you anything in their will, because they thought you were a weak girl.
They locked you in the basement of an abandoned factory and left you there.
Chifuyu and you were best friends who have known each other for a long time.
After a few minutes, you were able to get out because you had a small knife with you, which you used to cut the ropes.
