I think that it has too much romanticising of possessiveness? You now how that door was the last panel and at the center, of chap. 6 makes me think that Haru never leaves their house(the cage the title was taking about, though the author also insinuates that Renji's the one trapped in a cage, love, as denoted by the extra chapter and that bubble placement next to the narrative on the last page)... Also how, I don't know but for me, at that moment when Renji asked Haru to come with him, Renji kind of make him feel that he was the only choice for Haru granted he was recently assaulted and Eiji being a beaech. ╮( ̄▽ ̄)╭

Something about this makes it hard for me to swallow. -.-
