Ianto walked into the hub that morning and headed straight for the coffee machine. He hadn't had a coffee that morning and he was feeling rather irritable. When he came to the machine he saw a box of his favourite chocolates sat next to his favourite mug (thankfully empty). This made him smile as he made himself and Jack a coffee.
When he went up to Jack's office the man hole cover was closed, so Jack wasn't up yet. This meant he had set up the chocolate before he went to bed. Ianto set the coffee on Jack's desk and noticed a small parcel wrapped up in a red ribbon in the centre of the desk. He picked it up and looked at the label. 'To Ianto, please wear this today :) Happy Valentine's Day - Jack'.
Curious, Ianto delicately pulled the ribbon off and removed the paper. He took the lid off the box and inside lay a brilliant red tie. Ianto shook his head, still smiling and switched the tie he was wearing for this new tie Jack had given him.
He stood there, holding the box for a moment before placing the present he got for Jack (Courtesy of Martha) inside it. He replaced the paper and ribbon then removed the label. He took a piece of paper and a pen from Jack's desk and on it he wrote a new label, which said 'Jack, I'll wear the tie, if you'll wear this xx Ianto'.
Ianto took his coffee, sipped it and then walked back downstairs. The team would be arriving soon and they would need their caffeine.
When Jack came down from his office, Ianto very nearly dropped the file he had been carrying. He couldn't believe Jack had actually done it. He was wearing the UNIT cap.
