What does Ren mean by " there is not much time left"? Can someone explain it to me?

He said haru will not abandon someone he's the guardian of. So he assumes that once haru realizes ren's an adult he won't forgive him all the time. Poor ren's convened that once haru's 'brother' role has ended he'll be abandoned. ╥﹏╥

Thank, I think Ren don't really understand about Haru love for him (︶︿︶)＝凸

too true. ren's so childishly blind. but then again, haru's the same. he clings to ''ren's a child'' way too stubbornly. (づ￣ ³￣)づ

dude, ren is a child. he almost hooked up with his cousin cause he convinced ren that he'd become an adult if they did sexual things, and ren believed him. it's like the candy offer. and for all Ren's preaching about how he understands Haru, he doesn't. it's natural that Haru would struggle between not fucking a minor, and his love for him, as well as wanting him to have a family, and him being his guardian. then Ren got in a fight and couldn't understand why Haru was mad at that, and his injuries. of course you'd be upset if Haru came home all covered in scratches and bruises and he refused to tell you why. these two have a very long ways to go until it's an equal partnership

Yea.. True enough.. Wonder what will happen in the end? ╮(￣▽￣)╭
