Haruki knew that Jun had heard his shouted question, but there was no answer from inside the room.
One of the security guards politely asked the singer,
"Please, already have fun with your friends, you can talk to Jun-san tomorrow, dude."
Haruki glared back at the man. He would not give up.
The second security guard waved the singer away, lifting his chin and facing Haruki.
Suddenly the door opened with unnecessary force and the singer saw Jun's face, and it was red, sweaty and with a swollen mouth.
Haruki knew that face, Jun had just had sex with someone else! Haruki had been cheated on!
'Cuckoo cuckoo cuckoo ...' the singer almost heard the sound in his mind.
Much more humiliating than being betrayed. It meant finally realizing that he had been used by Jun for his distraction for lack of a girl to have sex with. As soon as possible, he was replaced. Replaced by what Jun missed in reality, a woman's pussy.
