Is he talking seriously?

"Boss, please! I beg you, I really need to use the toilet. It's my belly, sir." They heard the voice of one of Jun's men calling.

"Jun!" Haruki despaired. "I don't want to be seen like that!" The singer pointed to himself, thrashed, and his pants without a button. And outside, someone was imploring to have access to the toilet.

 He was going through a breakdown. 

To the singer's relief, he heard someone else's voice explaining,

"Sir, there's another toilet available. You can accompany me!" 

" Shss, "Jun shushed Haruki quietly, and hugged him. "It's over..." He kissed the singer's hair, lovingly.

Jun even helped him to look as presentable as possible in the given circumstances.

The two left together, as there was no way to hide what they had done there half an hour ago.

Haruki left crestfallen and worried, but quickly noticed that he needn't have worried so much, they were alone. Not even Jiji was around.
