@ terumi - I have to warned u though, saga planets scenario writer's story is very plot driven and deep, his writing needs u to dig the details by your ownself to get what the story is about, he doesnt explain things detaily, he relies on meta/symbolism a lot.
Personally , i dont think u shud go so fast into that kind of scenario yet.
Hmm.. i recommend Natsu no Ame since that one is one of the excellent slice of life/romance titles i have played.
