Eh, not really. Like >>119785073
said, it comes off as too weird. However, I do relate to characters whose flaws are the same as, or worse than, mine. It gives me some comfort. Likewise, the characters who deep down I wish I was like, but am not so they piss me off, I sort of “admire”. Both are amongst my all time favourites if they hit that sweet spot. A mix of power fantasy and seeing my worst traits reflected and recognized. There’s maybe one or two characters who fully manage to combine both aspects and they’re the closest I come to self-inserting but again, not really.
