interpretation of a FNF Soft Mod Senpai

this is sorta how i'd do it or just some general ideas based on the themes of FNF soft

First off, completely invert Senpai's personality where in reality he's a nervous and sort of clutzy writer who dreams of one day becoming a novelist or a mangaka if you wanna lean more into the japanese thing, also could be used as a means of drawing parallels to Boyfriend.

Maybe he has DID in a sort of Hulk sense, in that he has two distinct personalities in his body, his own and the "Glitch" persona that seems like a monstrosity at first, but really was born out of senpai's need to protect himself due to a less than stellar homelife, sorta like devil hulk to bruce banner in immortal hulk, The Glitch is moreso like a big brother to senpai, only really caring about protecting him and making sure he stays safe.

Maybe before he met girlfriend, he used his powers (Which are reality-warping in a way/maybe the worlds he write can actually come to life) to trap himself in a world of his own creation but when he got together with girlfriend he realized how great the world outside could be and started coming out of his shell.

Maybe his parents feared his power and abused him which caused his Glitch persona to manifest and escape that home situation or somethin idk?

Again just general ideas/guesses on what direction senpai could go in.
