Except the seme isn't really what you'd call a gangster but it's really good because they both learn from each other and the seme does defend him..tbh not really accurate but I still rec it!!!
I want some rec:
Where the uke is a typical pushover and afraid, while the seme is a bully-like (or gangster like) where he is strong and arent afraid of anything.
But, as they got close, both learn from one another. The seme teaches the uke to fight for what he believes is right (not an actual fight), but have a strong will. While the uke teaches the seme to be kind (not to everyone, but those he cherish).
That kind of plot? cause I swear that they many authors really like the typical cliche characteristics of uke and seme, but at the end of the plot, they are still the same, no character development, but just obsessing with each other.
