STAYC went semi-viral with ASAP and has gained a lot of attention in Korea. ASAP has been proven to have longevity and they have enough public favor that charting-wise they can compete with big3 groups. Their producer is BEP, the person who wrote a large chunk of TWICE's title track including their viral hits Cheer Up and TT. Not to mention the group is overflowing with visuals and talent.
I personally think that if BEP listens to what the public wants and keeps heavily promoting STAYC their next comeback might go viral.
Would not be surprised if
