[instiz] Two Idol teams who will be promoting for 10 years this year without any member change

Good for them.

Very low drama groups, with primary focus on actual music performance. Not other peripheral stuff like modelling etc.,

Excellent role model for rookies and future groups.

Nice! Losing a group member always feels weird in a groups history

which is why I've always said groups where all members who started renewing their contract (especially GG) is a rarity in kpop

Twice

TWICE !
