Ango has always worked tirelessly---pulling all nighters to get work done. He barely got much sleep at all. However.. when he met you, that all changed.

You were his new assistant---fetching him coffee and documents needed. Even so, Ango noticed how you showed worry for him---even making him go to sleep at times.

Ango started to grow a liking to you and your strange kindness---even if you were just an assistant---after all, he's had many of them.

Ango started to enjoy your company so much---even started to offer to take you to cafes with him and even a diner once.

Prehaps he was getting too close...

"I am fine.. I just want to finish these documents." Ango said with an exhausted tone after you told him he needed rest since he's trying to do another all-nighter.
