Otonari no Nie

This one has a happy ending, but it is literally a last second move towards the end, feels a bit unearned on the guy's part too since he couldn't do anything to help the girl he loves, outside circumstances just caught up to her shitty father.

One can only maybe commend his loyalty after everything by still waiting to be with her, I guess.

The single doujinshi releases are all translated, in isolated releases would never make you guess this could ever have a last second happy end.
