As I find myself getting into the groove of being a tactician, and the responsibility over lives no longer weighs heavily on my mind, I start feeling more and more responsible for the mental well-being of those I command alongside their physical well-being in battle.

News has spread to a small village of Renais that the world has been saved by the nobles and their followers after they managed to defeat the demonic horde that plagued the lands. Not only that, but three of the village's sons were part of that group that saved the world as well. So when one of those three knights rides into town in the deep of the night and comes into the local inn, the few people working there that are still awake give him a hero's welcome, even if he doesn't think he deserves it.

As a battle goes on in a vast desert, a young tactician and a young thief remain behind, searching the dunes for treasure. When they stumble across an odd potion, they figure they could either let a mage identify it... or they could just experiment, try it, and see what happens. And so, thanks to some goading from the thief and some bets, both of them try the potion... only to find it was a love potion. And so, both forget they're close to a battle, the thief forgot his grief about his slain lover, and the tactician forgot all the restraint they told themselves they'd show, and desire takes hold.
