who is devi??

Well, I don't know the full story either, but what I do now:

Nny and Devi met at a music store, I think? Meh...

Devi liked Nny because she thought he was nice.

Devi is an artist.

They went on their first date, and I don't know whether they kissed or not, but either way Nny felt so much love he felt he needed to "immortilize the moment" and tried to kill her.

Yes, she totally beat him up when he tried that.

Later, Nny called to apologize and tell her he doesn't feel love anymore, so he won't hurt her.

She totally swore at him, shouting, and told him that since that date, she hasn't left the apartment that she will find another "nice" guy who will do worse to her than Nny tried to do.

Sorry if this answer was confusing.

Her character is more developed in "I Feel Sick"

They met in a book store that devi worked at and nny would always visit her and eventually she asked him out and they nearly kissed but he freaked out and left and talk to the doughboys and they said since he was happy and that was rare he needed to preserve the moment and kill her so all there was was the beautiful begining never a horrible end and when he atempts to kill her shes not willing to take it and kicks his ass for trying then leaves since then she becomes scared to leave her house in fear he'll try something again and when he calls to appologize she yells at him saying all her hatered for him and how she can't leave because of him and awhile later he figures he won't really ever be called so he sets up a suicide device that'll shoot him if he ever speaks into the phone and right after he sets it up she calls him to tell him she's given up on being scared basically and when he answers he gets shot by it his sounds make her hang up and still not willing to leave
