There is a high chance of sex with Amelie in the next chapter 11, not because of this post, but because I know the guy, and how the story is going, hint drop, at the end of 10 there is the acting with Mia, and this is the element that will make Amelie Jealous and want to compete. She might confront the MC about Mia, and he might say that there was something before, she will get furious but she will compete. OR he will say that it was an acting, Amelie won't totally believe but another thing will happen with Mia in front of her and she will give in to compete. Amelie is not the toxic jealous but she's more subtle.
Nothing is guaranteed though but there is a high chance of sex at the end of the chapter 11.
