The first argument between a couple is always the best, or so I feel. Well, the best to write about in any case. So here we are. I will continue if you ask me to.

'Ronald Weasley, you, you...!" The angry tones of Hermione Granger rang through the common room early one Monday morning in the middle of the winter term.

"What in the name of Merlin is it now?" asked Ron, irritated, stifling a yawn, as he entered the common room in his too-small maroon pyjamas.

"You know jolly well what you've done!" came the reply.

"I have no bloody idea, 'Mione, you'll have to explain," said Ron, carelessly, turning absently to the notice board in the common room and ripping down the rude notes that had been written about Harry and Ginny the night before after they had been caught kissing in the Room of Requirement just before the last DA meeting.

"Well, if you can't be bothered to work it out, I'm not going to waste my breath on you!" shouted Hermione, and slammed out of the common room in a huff.

Ron sank wearily into one of the red velvet chairs by the fireplace, his head in his hands. He knew perfectly well what he had done wrong, although unfortunately he didn't really know how to amend it. He thought back to the evening before, sighing, and shut his eyes.

Dearest Diary, it had read,

It's been a pretty interesting day so far. We had to write about a muggle battle in fifty words today, and I've pasted it below:

His Last Battle

He charged, his sword clenched tightly in his hand, slicing the blade through the enemy, decapitating bodies. Reaching the edge of the battlefield, he slowly turned to look back over the scene. Death and destruction met his eyes. Nothing stirred but the wind blowing wistfully. He dropped his sword.

I got full marks for that, so I was especially pleased. Full marks in the Charms test I did earlier as well, cheering charms. It was revision for our N.E.W.T.S. Maybe that's why I'm feeling so cheerful.

Maybe it's because Ron grabbed me in the hallway and kissed me in front of everyone, or maybe it's because he gave me a little gift at break time of some tiny earrings that he bought for me in Hogsmeade. Well, whatever it was, I'm happy!

Sometimes I can't help feeling that he doesn't love me though. I love him with all my heart, but sometimes I just...well, he's rather immature and I don't know whether he's taking this seriously.

I must go and see Professor McGonagall about the Transfiguration homework she set-I've done it already and she just said to ask if I would like extra work.

Yours truly,

Hermione x

Ron had found the diary lying open on one of the tables in the common room, and just couldn't help reading it. He was saddened by what he had read, and determined to prove that he did love Hermione, so he'd written:

Sometimes I can't help feeling that he doesn't love me though. I love him with all my heart, but sometimes I just...well, he's rather immature and I don't know whether he's taking this seriously. I PROMISE YOU, MY SWEETHEART, THIS IS SERIOUS FOR ME. I LOVE YOU.

He had not thought about how Hermione would take this, being Ron Weasley, and had left the diary as he'd found it, but with those extra words.

Ron smiled ever so slightly at the memory of this, but felt rather ashamed and guilty. Finally, he decided what to do. He snatched up a pen and some parchment and wrote, hastily:

Dear Hermione,

I'm sorry about writing in your diary. It was lying open and I couldn't help but look. I try to be serious, but maybe it's not working. Maybe we should just call it a day.

Ron xx

Later that day, Hermione could be found in the common room bent over a piece of parchment, wiping tears from her eyes.
