@PURE PERV!!!! Everything you said is wrong and I will tell you why.
First of all, let's be clear on what consent is. Consent is an explicit and enthusiastic YES. It can also be taken away at any time if you feel uncomfortable or simply want to stop. In fact, the healthiest thing you can do while having s** is to make sure that your partner is comfortable and enjoying yourself.
You said that Sanho did nothing to stop Tak. However, can you please go back and read the story again and take note of all the times that Sanho clearly said no and told him to stop? And all the times that Sanho said that he was in pain and he was crying? And most importantly, have you forgotten the scene where Sanho is LITERALLY TRYING TO GET AWAY FROM TAK? He was literally crawling away from him. How is that not him trying to stop the situation?
What Tak is doing is coercion and LITERALLY FORCING HIMSELF ON SANHO.
Let's not excuse ra** simply because Sanho has feelings for Tak. Just because you like someone, it doesn't mean that you want to have s** with them or that you owe it to the person you like. You can like someone without wanting to fu** them. And Sanho expressed this clearly! He expressed his discomfort many times.
