Super op* not open lol
Overpowered* not open lol
I was into this trope a few years back and there are countless like this in mlm novels, particularly CNs! my go-to was always the Quick Transmigration tag because it was a lot of settings and possibilities in a single story that all tied up in the end (=・ω・=)
You should check out the website Chrysanthemum Garden for it if you're interested! It's been a while though so I can't vouch if the stories are as good as you'd want them to be, they're almost bl-slop for people who enjoy the same repetitive tropes but boring for people who enjoy more unique plots.. (；^ω^）
I wish there was an yaoi where the Mc reincarnates into a typical action novel where it ends with the Mc being like super open and has a harem yk the typical action novel that we all hate in action but anyways the Mc reincarnates as like a side character or a villain and ends up catching the attention of the ML aka the mc of the novel and instead of it ending in a harem the mc of the novel ends up falling in love with mc and the mc is like Hella confused lol cause the novel mc isn't following the plot lol I wish there was an yaoi like that it would've been SO interesting
