Summary
Recently, I was reflecting on something. You see, I feel as though there are countless instances where we do not realize that something has changed the trajectory of our very existences until much later on. It’s fascinating to look back on interactions or events that I didn't overthink at the time, only to now possess the insight to acknowledge how they would shape my entire being.
Hindsight is twenty-twenty, but the newfound acuity to my vision will not go to waste as I use it to gaze back on you, and on the time we shared.

Summary
Choromatsu had no complaints about his most recent assignment from Central Command, even if it was notably more dangerous than the previous tasks given to him. His only real irritation toward his mission was that he couldn't find anyone willing to accompany him and act as his research assistant. Needing someone to occupy the role, he decided to enlist his human captive, Karamatsu, to aid his efforts for the duration of the mission. Although his superiors would surely reprimand him for such a choice if they ever learned of it, he elected not to tell them and proceeded as normal. However, the assignment would prove to pan out in a bizarre series of events that would defy just about every definition of normal.
