What I have planned so far is that he pursued her while she was involved in a relationship with a married man. Eventually, she gave in and sat for him- there was an instant connection between the two and she eventually became his mistress as well. She is still with this married fellow, and the artist wants her to leave, though is not ready to commit to anything. I am open to any details you might want to add, especially with a character you have in mind. I'm fairly new to IJ - playing, though not new to rp in general. It's totally, totally open!
PB suggestions: Jackson Rathbone- I know people like to use him a lot, but I did like how he looked with Laura Donnelly in Dread, even though she had a massive and cool birthmark in that film Ben Whishaw- because he was all artsy pants as Keats in Bright Star.
Basically anyone lean and scruffy with a creative air about them :D
If anyone else cares to plot, on the other hand, I do Harry Potter, most musicals you might throw at me (no Glee/Wicked though), song-based PSLs (if I haven't heard of it, send it to me!), Shakespeare and fairytales (modernized even), and I also do Star Trek, though that is still a bit shaky for me if you don't mind playing with someone who has to constantly research when playing. I am most comfortable playing female characters, though I have experience RP-ing males. If you can think of anything else, let me know!
