This is the good path in the game, especially the non-romanced, non-ascended path.
The only thing, which doesn't happen is curing his vampirism, but it's mentioned in the epilogue that he accepts it as a part of himself.
Ahh, without romance I refuse... :)) Though I think it's even worse without romance there - Astarion just burns and runs away, and there's no one who cares about him in any way.
What I wrote is just a "fantasy on a theme" of how good it would be if it were :))
Without a cure for vampirism, in my opinion, it makes no sense at all and leads to the mockery of Astarion that we see in the game.
