is this the end? pls tell me theres more but not in the violent way

No, this is not the end. Haha.
But as much I know Yuta, he is not gonna nod on that surgery so easily or maybe… the surgery ends badly, I hope this is not the case. We still have a lot from the story, and I fear this is too fast to be everything smooth and happy considering the whole story. Too many unexpected things happened already, so I fear we have a lot ahead still.
