Since the details about this light novel are not widely known to me, we can only make assumptions. It could be that the main character is a high - school student who is quite ordinary in the real world but discovers extraordinary powers or abilities in the isekai world after school. There might also be a mentor - like figure in the isekai who guides the main character through the quests, and some interesting villains or rivals that the main character has to face during these after - school adventures.

You can expect a very relaxing time. Having coffee while reading a novel in such a place might give you a chance to escape from the daily hustle and bustle. The coffee aroma can enhance the mood, and the novel can take you to different worlds, just like the name 'isekai' implies, which often refers to another world in Japanese media.
I'm not familiar with the 'reijo wa mattari wo goshomo light novel'. However, light novels usually cover a wide range of genres such as fantasy, romance, and adventure.
