Have you watched Wotakoi tho? It's very accurate to real life otakus, anddddd also little bit of Romance(?). Idk just watch it if you haven't XD
I hope you would not want to check 'Alien' Difficulty, it's eye cancer.
For anime I would maybe recommend OreShura, as it is a good slice of life anime. It is also a harem though, and if you do not like that kind of stuff I hear March Comes in Like a Lion is nice, but U am oretty sure it is ongoing.
