These two came to mind but for different reasons,but are smutty af with hot and possessive semes, the first is super doting and the second is more sadistic. They're both obsessed with their ukes
What in particular do you like about taeju?? Unfortunately no one is gonna be just like him and he changes through the story do you like where he is now or more mid range? Do you need a character arc or can they always be doting, always be dominant, etc.

Okay this one for sure I think he's similar to Taeju in his personality (just not a gangster), I love this story

These all give me similar vibes in the couple dynamic... somewhat reluctant ukes (in the beginning ) with devoted semes
None of them are omegaverse though, I can't really think of any without more specific desired characteristics

This is the closest one i can think of...the couple dynamic is similar and its got the whole groveling trope. Takes some time to believe he can redeem himself but he does XD
Can somebody please recommend similar stories? I mean Taeju like seme...
