Just talk here. Responses may take a while though…
The Uboachan discord is comfy, that'd be a good place to start. Alternatively, you could just skip the bullshit and message someone as cool and caring as me right off the bat. My discord is ross_hell#4258.
Or look up for other yume nikki discords, if you're not happy with uboachan one: https://hujle.github.io/
But I must tell most of them are either barely active or as dead as this board.
Get irl friends online seems to be the best way.
Just don't fucking use /soc/
