Well for me I'm glad it when down Kirino route.
When I first started off I thought he was going to get back with Ruri I was say "don't do it" over and over again until he said he doesn't like her I was so happy. I was so happy for Kirino when he said that he loves her, the were going down the hard route but I was happy for them.
Then Manami comes along trying to throw all this stupid moral nonsenses just because she thinks it's wrong (hey, it's their life let them live it, it's not effecting you so why but in?). Then we find out that she loves him so shes been trying to stop Kirino for years. Kyousuke has never thought of her like that anyway. I can't believe she punched Kirino how childish can you get? After that they arranged a fake marriage then sadly broke up afterwards (Probably because society will be harsh on them, but who knows).
Anyway loved the OVA's was waiting of ages (felt like it). Full of sadness and happiness, great OVA 9/10
