[All] Lottery win? Will you tell the members?".. What will Ive choose?

On the 28th, the agency Starship Entertainment released the first episode of season 5 of their own content '1.2.3 IVE' through Ive's official YouTube channel.

The members of IV, who attended the Bulgama Jjimjilbang welcome ceremony as a special feature of their world tour return, walked the red carpet and announced the start of season 5 of '1.2.3 IVE'. They seemed flustered when they saw the red carpet at the entrance of Bulgama Jjimjilbang, but they quickly showed off various poses and acting, turning it into a photo wall. The members couldn't hide their surprise when they perfectly took on the challenge requested by those around them, with Jang Won-young doing the 'Emergency' challenge and Lee Seo doing the 'Tanghulu' challenge, showing a different charm from their stage.

Each of them decided what they wanted to do at the jjimjilbang, but contrary to expectations, they ended up trapped in a hot kiln and had to solve quizzes related to the members in order to get out. The first to successfully escape was Lee Seo. When asked, "If you win the lottery, will you tell the members?" Lee Seo was the only one to raise her hand, and she escaped, assuming that no other member would have raised their hands. Next, Jang Won-young, Ahn Yu-jin, and Lay answered the question in order, leaving only Leez and Ga-eul. When asked, "What's the most recent picture Lay took?", Leez showed her wit by answering "a selca" (self-camera), and Ga-eul ended up being the last to escape the kiln.
