@sherrynity I like how you think she consented when she didn't even have the chance to. She didn't know it was going to happen, they didn't talk about it beforehand. THERE WAS NO CONSENT ON HER PART WHEN THE GUYS KISSED. He cheated in that moment. She only consented after because she is portrayed as an uber fujoshi.
The thing about consent is that it should always be requested BEFORE you start on something, not after you've already cheated and are begging for forgiveness. The guys' reaction showed that they knew they did something wrong.
https://sapac.umich.edu/article/49:
"[consent is] a clear and unambiguous agreement, expressed outwardly through mutually understandable words or actions, to engage in a particular activity [in this case polyamory] "
"If you are unsure, it is important to clarify what your partner feels about the sexual situation before initiating or continuing the sexual activity [in case they gave consent before but show signs of having changed their mind]"
None of this happened and the world they live in is not portrayed as one where polyamory is the norm.
Grow up and think about what your words and actions mean. If you seriously think this chapter showed any form of proper consent you are a danger to the people you fancy.
