You can say he was faking it for the sake of the task but I don't think it was non consent. In the beginning of ths episode it was clearly shown that bison was worried that it would be too much for kant but kant kept on insisting him to carry on.
I wanted to love it but couldn't. It was going great till ep 7-8. I was enjoying all about it but then it went dowhill for me. Acting is damn good though.
I think shoma is really good at spicy scenes and kissing but since this is takuto's first project it comes off…
He was really not helping in that scene, I mean I get they wanted to show the typical dynamics of a bl couple where the bottom is submissive but boy that kiss was terrible, like he did even try kissing back once
