This is another breather episode and just like ep 5 it is also canon. The episode shows us a day off for GS, a day when there aren’t any goblin subjugation quests. There's also a brief returning appearance of the Hero from ep. 6. The letter that GS received from Sword Maiden practically sounds like a love letter😏. It's all light hearted and relaxing all throughout the episode until the scene at the end completely reverses it.
