Hi.This may be a spoiler so if you didn't see anime you shouldn't read.
First when you start watching this anime you are thinking hey this is another boring anime about relationship about brother and sister but after you seen few episodes you start thinking this anime is great.Great story, 2 specials,2 seasons a lot of good song Meruru witch i awesome good characters.But idk why the creator of this anime just completely destroyed ending of season 2.Last 2 episodes you thinking of finally he rejected all this girls who loved him and finally said his feelings to his sister but no.Question is why Kousaka after telling them he loves someone other especially Manami was destroyed totally stop loving his sister?in last scene we seen his wedding with her and after their kissing we hear that words you know what we must do?everyone start thinking o their go to bed or something like this.No they just stooping being in relationship.
Ending really suck and destroyed this great anime.I was felling like Meruru in planet buster destroying this planet.
