Your suspects are … ?

After reading the above clues my money is on the ex's father. No.5

He definitely caused their earlier break up and is concerned that his daughter is still in love with Laik. He is wealthy and influential  with Laik's agency and I recall Cheon Gwang Su [Se Na’s boss],  warning her of some corruption. He is trying to get her to leave the country. He is having her monitored and possible knew she had met up with Laik, however, who would he use to kill the victim???? I don't think the manager but then again he has cast doubt on Laik's innocence. I don't think the CEO he has been talking future contract and work for Laik. Even the youngest band member seems too sweet for such a fatal act.

 Holly:

• I stand by my opinion from the first episode: for me, it's the “manager.”

I think you are right. Who else has close access to all band members without scrutiny. Someone  drugged them somehow. The why? I threads of ideas but nothing solid. Lol such fun.

ep 7, if they're trying to be like 'when the phone rings' and not wanna show some SHOCKING PLOT TWIST, then i thinkkkk it's the ceo. jae hee was my first suspect but um he's all bark but no bite type of person, and since the ceo thinks of ra ik as like someone whom he can control, i think he's the one who killed woo seong. 

 Ivy:

I'm assuming La Ik was the actual target so I'm ruling out anyone with open animosity towards him. Looks like the angry bandmate will be exonerated next week, we'll be focusing on what he knows. My money is on the younger bandmate right now or the manager.

"I'm assuming La Ik was the actual target" I keep thinking the same thing since the start. Like he was supposed to be the target but Woo-Seong camein the way or something. I'm glad to know that I'm not the only one who thought this. 

From the very first episode I thought the killer was Lee Yeong Bin. I feel like he might have killed Kang U Seong by mistake or by accident. He had to deliver that final stab wound to cover up something and so that U Seong didn't suffer. Was he La Ik the intended target originally or did he kill U Seong by mistake? He definitely spiked the drink at La Ik's apartment prior to this. The question is why? I feel like the earring found was his ex girlfriend's. Either she gave them to him as a gift or he bought them for her. The question is why was it missing from his safe and who knew the code? I feel like she had an affair with one of the Gold Boys and that is why he is so upset with Jae Hui in the previews. I also think Yeong Bin approached Choi Jae Hui at his car and drugged him somehow and he drove off or perhaps he staged the accident after drugging him? Jae Hui was starting to realize things and he needed to prevent him from talking and figuring it out. I look forward to finally finding out soon.

 Mrs Gong:

I know this is crazy, but I think this way

That man was plotting with someone, and his accomplice ended up killing him.

Alternatively, I suspect that the dead body is not actually his. Although we believe he is dead, he may still be alive and deliberately deceiving everyone.

That could very well be. Maybe he thought it'd get Laik out of the binding contract? But I am also suspicious of the younger band mate. He has no true alibi, he could have a motive as well.

i think atp it should be hye joo

Honestly, this is so disappointing. I didn't want it to be Hye Joo or the Manager because I thought that was way too obvious... But here we are
