a self insert manga is usually when you make a very generic character with no discerning personality , give him mary sue status and overhype/ overpower him for no reason
Initial disclaimer: i've read first three chapters, got cringed, and proceeded to leave a comment.
Main stuff: yeah, no shit. It also quite often is (at least from what i've seen) an opportunity for the authors to present themselves in a better light to their readers, and-or an attempt to make them feel better about themselves, especially in amateur-ish, self published works (meta-narrative-
like devices and tropes notwithstanding). In that case, i assumed the artist did exactly that by giving himself* literary version of sim girlfriend to "interact with", and by simultaneously putting himself in the story as a
sort-of first perspective person narrator ("next level"). All that crumbled of course, when i've read first chapter of the second volume, where narrative point of view changes.
That's the rough sketch of thought process behind my first comment.
My guess is (reason being, the way you pointed out the significance of "love squad"), you assumed i thought that "self-insert" means the variation of "audience surrogacy".
*i also assumed gender because of the name, how wrong of me
this is a twitter webcomic, there isn't much depth to it
but you still managed to misunderstand it?
here we have a twitter webcomic about a girl blushing
I fail to even fathom how you came to the conclusion that this is a self-insert,[...] but it really boggles my noggles how you can possibly say that. On a twitter webcomic.
I'm not trying to diss you
Really now.
