Comment by subtlelove_jones on Crucial Point - Chapter 48

@subtlelove_jones no he did not, he broke it to scare Wookyung. Never intended to hurt him with it 
He is trying his best to make Wookyung realise how fuc*** up he is and Wookyung is loving the roughness refusing to stop or see its supposed to be a play and not physical abuse

@Itachi Sure let's say he broke it to scare Wookyung but Heewon as a Dom should have know when to stop. He kept going when Wookyung refused to say the safe word causing him to end up in the hospital. The safe word is not only for the Sub but for the Dom too.
