"You were with Himari last night!" Gael deducted and clapped his hand. "Hah! I bet you and Himari had a date yesterday!"
Dice and Vincent gasps when they also realized it.
"Oh shit! The greasy detective is right! How would you know that Himari had an accident last night? Because you were with her when that happened!" Dice exclaimed.
"Damn! The old detective still has working brain cells inside his head!"
"You brat! You dare to insult my impressive intelligence?!" 
Jin suddenly has a headache because of these three. Jin feels as if he is currently surrounded by unruly kindergartens. After massaging his temple, Jin stands up from his seat and goes straight to the door.
"Jin, where are you going?"
Ignoring their calls, he shuts the door with a bang and walks to the elevator. Since he is already here, he might as well go to his own VIP room to take a shower. He presses the button and waits for the elevator to bring him to the right floor. But after passing the three floors, the elevator door opens again. To his surprise, the man in the gray suit from before entered the elevator again.
Perhaps the man did not notice that they had ridden the elevator twice and quietly pressed the elevator button. Jin ignores him again and avoid looking in the man's direction. When they finally arrived at Jin's floor, his phone rings again destroying the peaceful silence around them. It was Himari who called him again.
"Why are you calling me again, Himari?" Jin said. His voice is now laced with irritation.
(Why can't you answer my calls like a normal person? At least try to be sweet and gentle towards me, Jin. Try it.)
"You—"
(You can always call me with sweet pet names like babe, honey, sugar, love, or my life. Do you want me to teach you how to do it?)
"Fujimoto, I am not in the mood to joke around with you."
(You are always not in the mood to indulge with my quirks anyway. But don't worry. You are still handsome.)
"So you are aware—"
"Excuse me!"
With a frown, Jin turns around and sees the man in a gray suit behind him. Did he just follow him here? When the man noticed the questioning look Jin is giving to him, the man did not waste any more time and asked him a question.
"Forgive me for my insolence. But are you an acquaintance of Himari Fujimoto? Is she the person you are talking on the phone with you right now?"
Jin did not respond to his question immediately. He first looks at the man with keen eyes. Though he tries not to show it, the man appears to be both excited and nervous about finally finding the person he is looking for. Jin is contemplating his next move when he hears Himari's voice on the other end of the line. 
(Hmm... Is that Ivan Hernandez?)
"What?" 
(Ivan Hernandez. The person who bought Shiri's music sheet. A tall and slim man who loves to wear a suit and has a beauty mark under his left eye. He is also a handsome guy, but I still prefer you over him. Ooh! Did I cause your heart to skip a beat this time?)
Ignoring Himari who is acting like a high schooler again, Jin looks at the man named Ivan again. He is still patiently waiting for him to answer his question. No wonder his name is quite familiar to Jin. He had previously seen his name on their list of auction attendees.
At first look, Ivan may look so cold but he does not seem the type of person who can harm others. But still, he should not judge other people based on their looks. Jin knows that people tend to fool others with their appearances especially in his line of work.
"...Do you need something from her?" Jin carefully asked. 
"I want to meet her—"
"Why?" 
"That's... I want to ask her about the auction—"
"Auction?" Jin asked. "What auction?"
Ivan closes his mouth after asking his question and does not attempt to explain anything further. Perhaps he is assuming Jin is unaware of the black market auction. Only those who secretly received an invitation from Lester Lim are permitted to attend the auction. These invitations are extremely difficult to obtain, and they are typically extended to people with a large sum of money to spend.
If Jin inquires about the auction, Ivan will immediately assume that he has not previously received an invitation to the black market auction. Jin never made an appearance at the auction. He is either always inside their viewing room or he inspects the entire facility while wearing a mask, just like their other guests. 
According to the reports he received from Lester's assistant, Ivan Hernandez is just a newcomer to their black-market auction. He only participated in it because he received a notice that Shiri's music sheet. After checking his background, the reports said he is quite obsessed with Shiri. He is willing to spend a huge sum of money just to buy Shiri's compositions. Thinking about it, Himari was the one who brought Ivan Hernandez to their auction. 
(Let me talk to him.) 
"What?"
(Let me talk to Ivan. I also have things to tell him anyway.)
"Do you know each other?" Jin asked.
(Who knows, right? Just let me talk to him. And don't be jealous, babe. You know that I only have you in my heart.)
"You are crazy, Fujimoto." Jin said which received a jovial laugh from Himari. Then he turned his attention to Ivan again. "Himari is on the other line. She wants to talk with you." 
Before giving his phone to Ivan, Jin presses the loudspeaker button first. Ivan carefully accepted the phone. He also cleared his throat before speaking with Himari.
(Mr. Ivan Hernandez, right? I heard you are looking for me. So may I know what do you want from me?)
"Good day, Ms. Fujimoto. I will go straight to the point then. I heard that you are quite close to the music genius, Shiri. Is that true?"
(Oh my. How did you know that? Did you conduct a background check on me?)
Jin is also thinking the same thing. If he is not mistaken, the first time they discovered Himari knows that musician was when they were celebrating the success of their previous auction. Even the two crackheads were surprised to learn that she knows the famous musician. 
"No, no. You are mistaken, Ms. Fujimoto! I did no such thing!" Ivan quickly denied it. "I just heard it from a woman who was passing by at that time. She was talking to her boyfriend about how incredible you were for being friends with Shiri and I just happened to be there so I heard it all."
