can someone give me some recommendations of a character glowing up ε=ε=(ノ≧∇≦)ノ

it could be any type of genre like Yaoi~Shoujo~ or school Romance .- TBH I need some bad bitch inspiration. Lol
a story plot where a lame person has some type of glow up and turns into a bad bitch. and becomes relevant, ( if possible., I would love a list of good Manga like that to read
ε=ε=(ノ≧∇≦)ノ (●￣(ｴ)￣●)
