The festival scene showed everything from water gun fights to abs reveal.

I participated in the Songkran Music Festival in Thailand, and it seems the weather was incredibly hot right from the rehearsal.

It was so hot that I would say it was the worst heat I have ever felt in my life.

It was pitiful yet cute to see the members shaking their heads, saying it felt like they had stepped into a sauna cauldron.

The members were also spotted joking with each other in the waiting room before the performance, asking if their abs were ready.

Wonbin seemed to have let go of his worries, saying he was planning to get thoroughly soaked on stage.

Eunseok promised to show off his abs properly at the Waterbomb performance in July.
