Idol Group 4nemo has a problem. One of the members, Aether, had recently decided to join his sister in the idol duo ✪utlanders, leaving 4nemo in the process. Now they need to find their fourth member, otherwise, they'd need to rebrand-but even that is a challenge. Because of this, the members decided to put the group on hiatus in the meantime, to take the break as an opportunity to catch up on school, bond with friends (whatever is left of them, at least), and maybe, find someone who could fill the hole that Aether left. Luckily for the famous idol group, they might just find someone they're looking for.
