Cover art for Juliet lyrics by Sonata Arctica

Very interesting thought, I didn't figure out for myself but now you said this I am perfectly with you. This could be about how he discovers that she doesn't love him anymore. The story might be that he wanted her to die with him, she agreed to be freed of him and his obsession and let him drink the poison while she didn't. When he figures out he calls her a whore and begins to hate her, which explains pretty much why in the end he is going to kill her in "don't say a word". Yet, if that was the story, there are still missing a few parts. Why did he survive? How does he get caught (for in "the end of this chapter" it says: "The promise they made, I should keep? Make sure that we would never meet", which I assume was a judgement)?
