I didn't start to read, but the comments make me feel like it already end, but it is market as "ongoing" ( ̄∇ ̄")
Yes. Not all stories need 80 chapters. Some end early and some don't end, even if they have nothing more to tell.

I think the art style are adorable, but same-face syndrome hit hard here. As someone who draws I know how hard is to corret it and can't judge at all, but it is possible. Don't get me wrong, everything looks amazing, but everyone look the same. I got a little lost. The stories are short and cute, nothing to complain about ╮( ̄▽ ̄)╭ ♡
