The Doctor put down his pen and read the letter he had just written. Then he reread it. He read it over about ten times, making sure everything about it was perfect. After the tenth time, he decided it was all good. Now all he had to do was deliver it.

He flew the TARDIS to her house. He didn't want to give the letter to her in person. He didn't want to be in her presence while she read it. He dropped it in her mailbox, and hoped she'd read it soon. After he dropped it off, he didn't see a point in sticking around and being nervous, so he traveled a little, to ease his nerves. He'd be back the next day, after she had, hopefully, thought about his message a little.

Clara woke up early that morning. After she ate her breakfast, she went outside to check the mail. There was the usual junk, but there was also a letter for her. Excited, she ran back inside and opened it.

She pulled the letter out of its envelope, and looked at it. She was expecting, well, she wasn't sure. But this wasn't anything she had expected. This letter was just a bunch of random circles. They looked kind of cool, she had to admit, but they didn't mean anything to her.

The letter was from the Doctor though, so she knew it had to be important. But she didn't understand it. She decided to ask him about it when he came back. She hoped that would be soon, she was starting to miss her doctor.

After interrupting an execution, and probably accidentally marrying another monarch, the Doctor returned to Clara's house. Her knocked on her door, excited to hear her response to his note.

He saw her face as she opened the door. She was happy to see him.

"Hello Doctor," she said, smiling.

"Well, Hello Clara," The Doctor replied. He walked inside and closed the door behind him. He started to walk through her house while he asked, "So, what did you think of that letter I sent you?"

"Oh, right. Yeah I was gonna ask you about that."

"Oh? Is that so?"

"Yeah," Clara got out the letter and showed it to the Doctor, "What does this mean?"

"Well I'm not entirely sure what you mean by that." The Doctor thought maybe she didn't understand what he was trying to tell her. Maybe she couldn't grasp what he was feeling. Or maybe-

"I can't read it. It's just a bunch of circles."

The Doctor's mouth hung open as she said this. He looked at the paper and concentrated. How could he be so stupid! Of course she couldn't read it. He wrote his note in Gallifreyan.

"Oh dear, I- I seem to have written that in the wrong language," he stammered, thoroughly embarked with himself.

"Right. Yeah. So, could you maybe tell me what was on that letter?" Clara asked. She was really curious about what the Doctor had written.

"I, um, I could, yes." The Doctor wasn't sure how to phrase what he wanted to say. It took him hours to find the words for that little letter. And he wasn't prepared to send his message orally.

"Ok, so just tell me."

"Right, yes, that is what I am doing right now. Ok, Clara, you are... An amazing companion."

"Yeah, so? What does this have to do with-"

"Please, just let me finish. So, as I was saying. You are an amazing companion. You are just... Well... Fantastic. And I don't know how else to say this. And that's weird for me, because I know how to say a lot of things."

"I don't... Where are you going with this?"

"Well, Clara, what I'm trying to say is... I love you."

Clara was silent for a minute. She had to process this. After she was sure she had heard him correctly, she asked, "You... Love me?"

"Yes, I do. Now I understand if you don't feel the same way, I mean I'm old and-"

Clara kissed him to shut him up. "I love you too."
