If its related to rabbits:
Sejun will trigger a harvest festival, where they will have most farmer rabbits scattered in the black tower. There we will know the history of the rabbits (black, white and gray) and their home floor (55th). It will be one of the first towers that Sejun will save and Black rabbit will have a love life, but that means he will be moving out of the 99th floor :(( along with the other rabbits (to start over in the rabbit kingdom). Thats mostly when their interactions end.
There is a very heartwarming scene in the latest translated chapters though, when Sejun was celebrating his 1st year in the tower and he reunites briefly with the OG gang with the parent rabbits, and they eat the first meal he was able to make at the cave. It was so heartwarming.
Yes, he will have that ability (by opening land deeds). The first time he left was kinda scary, but the story itself is just chill so everything works out in the end. There's a big plot coming in but its not at all the focal point and even at 1st year anniversary of being stuck in tower, everything is mostly sunshine and daisies ヾ(❀╹◡╹)ノ~
Currently, he is still growing the group, but the ones with him daily would be Theo and Cuengi. There are many new friends we will meet along the way, I'm actually excited how it will be illustrated bec the cute animals are all claiming Sejun's lap .
Theo will be on his right knee, on Theo's tail is Iona the hamster wizard. There is golden bat in his back or shoulder, Cuengi on his lap, Flamey the apple tree on his shoulder, Fenrir on his pocket, Piyot the bird on his knees or back and Ajax the white dragon.
99th floor is peaceful (even the western part in the latest chapter where the corrupted beings were in - there are many chapters dedicated to Sejun trying to clean up the western part of the 99th floor). The minotaur king is protecting the waypoint still, but there were times where he and his army went down floor by floor for a quest by Sejun.
There's really no focus in romance, the closest hint we get in the latest translations are Aileen being jealous. She's hundred+ years old as well.
Come to think of it, she doesn't have much relevance in the most recent chapters too aside from just appraising and looking out for Sejun's skills.
In terms of mental maturity, we can say she's been growing up fast in the sidelines as well, as she keeps training her dragon heart.
I'm not really focused in the romance because as I've said, its not really the main genre, not even a subgenre tbh. The hints of romance is very very negligible to be bothered about.
SOMEONEE NAME THE RABBITS, BEAR AND THE BEE PLZZZ I DON'T REALLY LIKE TO READ "SICKLE RABBIT" feels disrespectful to me(〒﹏〒)
