"I was banished by my childhood friend from the party but turns out i was super strong and so i decided to get revenge on them all but turns out they had good intentions and thought they were holding me down and just wanted to raise my low self esteem??!?!?!?!?" You can also add a sentence about harem or something"Gives author more ammo"
actually, there is a manga about banishing (I forget about the title if you guys could help me with it) about this dude with support magic, double XP and boost party ability. he got kicked out by his party not because they hate him or he sucks but because they worry about him going with them into a dangerous area so they give some compensation to him like a land (island) for him to govern.
It's this one: https://mangadex.org/title/2436b0ca...-leveling-up-the-hero-to-leveling-up-a-nationIt's the cycle.
Something become popular.
Copycats appear until the 'genre' become cliche.
Someone make a new thing to break the mold that get popular.
Repeat.
In fact there's already 'the banisher had good intention all along' manga already.
Praise the lord, and pass the ammunition"Gives author more ammo"
