Indeed no one checked their phones as their hands were full with tasks except for Wang Yoon Gi, who was simply toying with Choi Sa Na to know what scheme she was cooking up. The bored Yoon Gi took his phone out and nodded his head at Choi Sa Na as if he was listening to her.
He noticed the message in the group from Chin Hae. 'Guys! Something is not right in the restroom. Come over if you have not heard from me in 5 minutes.'
It has been ten minutes since the message, and there was no follow up from Chin Hae. Yoon Gi narrowed his eyes but concluded if something being not right in the restroom was related to Chin Hae, and there could be only one brazen bastard - Moon Chin Hwa.
After concluding, he turned toward his girlfriend and fiance, hiding on the side as they eavesdropped on his conversation with Choi Sa Na.
