Man, Sentarou really deserves better and much more.
Ririko and Touma barging in to a low point of his life made him more miserable than he already is.
There's also the issue with Meguru. While Sentarou could potentially become a good paternal figure for the kid, it doesn't change the fact that he was forced to take care of her. Also, knowing his personality there is no way he would refuse her.
I know bad boys/girls x doormats are so hot right now, but I am still hoping for a twist where Sentarou gets his happiness somewhere.
Rant aside, thanks for the release!
