R.Ren is basically the half of Ren's personality that wants to do all of the things he'd never get himself to do if he was his normal self (save for the fact he's still unemployed), so there's no limit to what he could do in his free time, unlike L.Ren.
The one thing he would want to do the most though is spend time with what's left of his family, including his children.
R.Ren still hopes that his normal self will bother to do these things within time.
Enjoy! :D
This is still open, so ask away!
