A story about a gentle nobleman who journeyed from one fantasy world to another fantasy world.

He receives no particular blessings from the other world, nor does he encounter any fundamental dangers.

Until he can return home, he lives an idyllic daily life as an adventurer, all while his utterly aristocratic demeanor constantly earns him double-takes.

Male camaraderie. Deep bonds of friendship.

There are enough descriptions reminiscent of Boys' Love (BL) to warrant asserting that there are no romantic feelings, so those who dislike such content should please refrain.
