Looking for a large collection of transcribed love letters

I had this idea that is mostly a pun. I want to train a Love Language Model (LLM) on a large corpus of love letters and/or poems. Tricky bit is to find a large collection that is available. Any advice on sources of transcribed love letters?

Edit: so far I've scraped a few website and downloaded a dataset from kaggle. I think it's enough for a just for fun project :)
