I've read the novel until chapter 200, and it's funny that with that amount of girls having a crush on him, he treated all of them, and I mean ALL of them, like little children. He gave them praises, patted all their heads, he's so fatherly
The only one that affected him is...
SPOILER!!!!
...
...
...
... Lysinas, the long dead dragon comrade from 5000 years ago. And even then he only realized it from a rediscovered notebook of Lysinas, and he's absolutely shocked to read THAT confession LoL my man so dumb dumb.
Also, this is one of the comics where I don't mind all them girls crushing on MC. Because they all stay crushes, for now. All these girls, and all the students basically, really do focus on their school life, and I appreciate that. It's like reading MHA but less chaotic.

...Mary is so small. I think even her mother is taller, like maybe Alicia's height? Mary is SMOL she's so CUTE (looking at her height difference with Adi is like looking at my short sister and her tall husband LoL).
Also finally they got married and Adi confessed! And Mary is oblivious no more!! Seriously I can't handle anymore of their married-for-years act with each other. Now they're actually married so it's no longer an act hahahaha

About the MC:
1. He's a very social and outdoor person. The type to play outside as a kid rather than playing video games inside.
2. He doesn't know much about fantasy lore. Everything he knows are mostly secondhand knowledge from his otaku sister's ramblings. (That's why sometimes his logic is everywhere because they're all assumptions and imaginations.)
3. He worked as a high-end cleaner for rich clients. He even has clients specifically asking for his service.
4. He can't communicate with everyone from that world. Yes, he didn't think of auto-translate magic (yet), BUT even if he did, for plot reason, he won't be able to communicate anyway.
5. But how did the golems and the animal followers sometimes understand what the MC is describing? That's because MC unknowingly telepathically sends images to others. No, it doesn't work the other way around.
6. Those "amoebas" are elemental spirits, signs that the forest is healing. Slimes aren't really a thing outside of fantasy medias, right? Only those toys we play as a kid. So no, MC wouldn't have known to call it a slime. Even I would call those amoeba-shaped things amoebas.

Hey question before I continue reading does any of the kings of the forest become human and join in his harem(if he eve gets one) it's happened so many times and now knowing that all the kings are female it does not help with the anxiety of the future. I would like it more if they would just stay as pets and nothing more. So please tell me do they stay in their animal form??

In my pov, i don't think that's possible. Didn't mention any nuance of it in the spoilers too. They seem to treat him like a parent figure or care taker. Koa got hitched with chai, the direwolf king, he's a guy. They had many pups.
It's a fun read. Frustrating cuz he couldn't understand what they're saying by words. Satisfying when the evil kingdom's side get what they deserved.

That's the best revenge ever for that old man. Moments before he die, knowing that his actions caused the clan to be nearly exterminated, that his crimes were exposed to his entire family to hear, that upon his death, if his crimes were confirmed (which it definitely will), his body will not be buried at the clan's family burial ground.
That ultimate despair moments before his final breath is what he deserved.

At the end there, I honestly thought a Jorougumo is going to appear or something. Because you know, the guy appears to be "in heaven", probably got his vitality sucked. Then there's a girl and spiderwebs.
Okay...I might've read too much yokai lores. But seriously, I bet I bet the next pet to be spiders.
United in extremely dire circumstances
United in their treatment of their students
