I don't have anything against Ren being manly and dominating and him pushing Haru down (it's interesting actually) but I really want him to be an uke when the time comes. It's also the vibe I'm still getting from the manga. Those characteristics I've mentioned are not necessarily equivalent to seme after all. I think him wanting to be more mature is about wanting to be simply at equal standing with Haru, a partner.
