Which K-pop group had an amazing run of four comebacks?

i think in general people don't count dilemma in the run and consider it a trilogy, which is a shame because ialso consider it a 4 part masterpiece! but i think naeun not participating in dilemma + the song not being received with as much praise as the others, knocks it out of the legendary run.

Yeah I think you might be kinda right, but I love Dilemma, might actually be my favorite of the run. DnD isn't as great as the previous 4, but still good

I had the exact same thought: "I'd nominate the Apink trilogy but OP wants four so I can't".
