Which project group you liked the most and would like to see again doing a song?

When I am saying project group, I am not talking about survival show groups that stays as a group for a while under a contract and has more than one song (which eliminates Super M and GOT The Beat) but, the ones that do only one song and never become a group again. Personally Wow Thing group made me really sad that it was an one time thing the members had a great chemistry together 🫠

For example the ones I remember from top of my head;

• YOUNIQUE UNIT (Hyoyeon from Girls Generation, Taemin from SHINee, Henry from Super Junior M, Luhan ex-EXO, Kai from EXO, Eunhyuk from Super Junior)

• Girls Next Door (Moonbyul from MAMAMOO, Seulgi from Red Velvet, YooA from Oh My Girl, Sujeong from Lovelyz, Sohee from Nature, D.Ana from SONAMOO and Somi)

• Wow Thing Project Group (Seulgi from Red Velvet, Chungha, SinB from GFriend and Soyeon from (G)I-dle)

• Triple T (Hyoyeon from Girls' Generation, Jo Kwon from 2AM and Min from Miss A)

• Honey Bee Project Group (Hani from EXID, Luna from f(x), Solar from MAMAMOO)

• Good Girl groups for example WITCH unit (Hyoyeon from Girls Generation, Cheetah, Yeeun from CLC, Jiwoo from KARD and Jamie)

• 4Tomorrow (UEE from After School, Gain from Brown Eyed Girls, Hyuna from 4Minute, Seungyeon from KARA)

• Mamadol (Kahi from After School, Jungah from Jewelery, Byul, Eunji from Baby V.O.X, Jyuni and Sunye from Wonder Girls)
