Kpop boy groups that sound like “regular” boy bands

My friend said she is nostalgic for boy bands and wants to try getting into kpop boy groups. I sent her a playlist of songs by some popular boy groups, but she responded asking if I could recommend her groups that “just sound like regular boy bands.” For examples, she gave One Direction, Big Time Rush, 5 Seconds of Summer, and Jonas Brothers.

I was never a fan of western boy bands as a kid, so could those of you who were fans of one or more of these groups suggest what you think are the most traditionally “boy band-y” boy groups I could recommend to her based on what she’s looking for?
