Members that returned to a group after officially leaving

I'm not talking about members who were on hiatus and came back, there was literally an announcement that they'd be leaving the team, but they actually did return. Here are some examples:

Mark (NCT Dream) (and NCTzens don't tell me he didn't officially leave, SM made his "graduation" from the unit a whole concept but then he is back again one year later)

Sunmi of Wonder Girls

Saem of Rania

Heesun of Pink Fantasy (her situation is weird because she came back as a "guest" member, but if you're still promoting with the group after you've left, I think that counts)

Ilgoon of Tritops

Any others you can think of?

Euaerin from 9muses

True! Although I think she was just on hiatus

Quote from catzi

Wonho after him and all the rest of MX come back from military

I hope so! That'll be some time though for something that will probably not happen

Quote from catzi

It has to!!! I know mx ot7 official reunion will happen soon or later this thread increased my hope lol

We'll hope together

does leaving company and signing deal with other counts too?

then we should include Taecyeon because people didn't believe that 2PM will make comeback in full squad, yet they did, even with members being signed by different agencies.

I would say no because he never officially left the team and they made it clear pretty early on that he had intentions of staying a part of 2pm.

Jessica Jung... But it happened in a crazy dream that I had .

I don't know if I should laugh of cry

Quote from RobVel

Btw, Heesun looks amazing in the recent comeback of Pink Fantasy *poison*!! She looks intimidating and elegant like a wolf!

tbh they never should have announced her departure. She never missed a full-group comeback with the group.

Now I want Yubin, SangA, and Aini to return after leaving because they were great members and I totally miss them. Yubin and Aini are still under MyDoll so it definitely could happen, but I will support them no matter what.
