I need help!

Ok, I'm coming up with a story staring Derpy and Doctor Whooves, here's the description: 'The Doctor finds out about Derpy's true feelings towards him, but when another companion from a different universe shows up, asking for his help to defeat Discord and in the process Derpy becomes discorded, is it to late for their relationship?'

Its going good so far but I'm having a little trouble with the title... ok a lot of trouble with title, I came with 'I love you Doctor' but I don't think it fits to well... that's where you guys come in!

Suggest some idea's for a title and I'll use the one that fits the description best, goodbye, good luck and merry christmas!
