i understand everyones concern with the situation going on in the story. this is not a scenario most people can imagine themselves willingly entering, but for wookyung its what he's been asking for the WHOLE story. He wants to see how far he can push himself.
wookyung can say the safeword at any time to make it all stop, and thats exactly the outcome they want.
please go back and reread chapter 83, guys :(
