Love's chronicle. Just like a chronicle records historical events, a 'love's chronicle' can be seen as a record of the events in a love relationship, in a rather poetic and grand way.
You can also say 'relating a story'. This implies sharing or communicating a story in a more connected way, as if you are relating the events to someone. It gives a sense of building a connection between the story and the listener. For example, when you relate a story from your childhood, you are not just telling it but also making the listener feel as if they are part of that experience or at least understand it on a deeper level.
At the tale's finale. This is a more dramatic way of saying it. It emphasizes the finality and grandeur of the end of the story, as if it's a big event. Just like in a movie, when the final scene is really important and this phrase can capture that feeling of the last part of the story being significant.
