Is it just me or does anyone else think that Haru was a bit too abrupt with trying the whole finger thing? Like I understand Ren wanted real sex but he definitely could have eased Ren into it better than bending him over the bathroom sink. I felt like it was more of a lesson for Ren to not ask for it than Haru really wanting to try it. It was a weird action coming from a guy who was constantly worried about Ren being a child. In reality, it's not even about Ren. It's more about Haru being afraid of the next step in their relationship. Seems unfair to Ren.
