It was your birthday!

You had received lots of greetings as you made towards your desk, few detectives even engaged a little conversation with you.

You could notice Sixty envying it, as if he almost looked jealous every time he walked by. You haven't been exactly cooperative with him, and he was the same. You could never get your work done, especially when you're working with him. You're his enemy, and you were the same.

Once you finally arrived at your desk, there was a cup of coffee with a note in it. Assuming that it came from anyone but Sixty, you were mistaken.

"Happy birthday, Detective. -Sixty"
