Minutes had passed and yet the rest of the Attack Team were still to wake up. Fortunately, the grumbling sound of Yojiro's stomach broke the awkward silence—getting the attention of the bored af Pedro.
Yojiro can't help but force out a smile in response that consequently made Pedro burst into laughter.
It was a bit embarrassing for Yojiro but he had no choice but to remain silent in response since it was Pedro who was able to hear his stomach grumble.
Well... He can say an excuse or two to other people but he can't do so towards Pedro because he was like his boss—his employer of some sort.
On the other hand, Pedro calmed down after noticing that Yojiro was feeling embarrassed based on the reaction on his face.
Pedro knew that Yojiro was indeed hungry at that moment. But, he does not know the reason why Yojiro did not inform him about his satiety.
