OK, so I just want to take a moment to say I get why people are frustrated with Yi-young and think she's dumb, but I beg to differ. I think she's desperate. Imagine having three months of your memory erased. Then imagine that you were severely traumatized to the extent that your mind felt it was better to suppress than to keep the memories. Then imagine that as you start to piece things together, it looks like you killed someone. Then someone comes along to help, but he's keeping things from you too. But then and even sketchier dude in a bucket hat tells you he knows the truth.

Wouldn't you do anything at this point to find it out? I get that she was naive to blindly give him the pen, but really, I can't fault her for it. I would be that desperate too. And honestly, to me the fact that she keeps doggedly going after these memories is admirable to me because at this point it's pretty clear that no matter what her role in Kim Ian's death was, no good can come from remembering this event. Yet she keeps pursuing the truth. I don't even know if I could do that much. Yes, she's naive, but I really don't think she's stupid. She knows when to show her cards - ol' bucket hat just managed to get a peek at her hand and knew exactly how to play her. I also get why Yoon was angry at her because it is frustrating to see someone do dumb things for good reasons, but it's even harder to see someone do dumb things because they were manipulated into doing so.

I also have to agree with @missvictrix on this though: "Let Me Hear Your Song has put a lot of effort into letting us know that Maestro Nam has some buried secrets, so if he’s not involved with an appropriate level of badness, at this point I might actually be disappointed."

I thought it was an interesting reveal that he claimed to be close to Kim Ian. Whether or not that's true is something I want to know. And more than that I want to know more about his dogged pursuit to the get to the top of his game. I want to know what part of his soul he sacrificed to be there.

I think there's an interesting parallel set up between him and Eun-joo, because she too has a dogged pursuit to get to the top as well, but it seems that even she has her limits in regard to how far she'll go. Both of them genuinely seem to care for the music for its own sake and not for the power games, but they both also see that proximity to power is the only way that they can get to the positions they aspire to. I personally really love the character of Eun-joo in that she's an ambitious and genuinely talented woman who is villainized for those very things as ambitious women often are.

I think that Grandma plays an important balancing role for the character of Maestro Nam. Without her, he's a shallow opportunist who cares for no one but himself. With Grandma, he's a hard-working young man who worked doggedly to get ahead with limited means and a cheap cello. Now we know that Prof. Kang chose him to study abroad, and that somehow entangled him with money laundering. Since he met Kim Ian abroad, I wonder if Prof. Kang also used Ian in the same way. (Beats me how you get money laundered by paying tuition abroad, but hey....) He's insisting that Kim Ian was his only friend and insisting that he really cares for YY. If he does care for YY, it's because her innocence reminds him of his best self. So I'm inclined to think that Maestro Nam knew Kim Ian had taken something incriminating and that Prof. Kang and co. were planning something dangerous to get it back. I think he set out to rescue his friend, but YY spoiled his plan by kicking him in the gut and grabbing his knife. I bet she cut herself and Ian free, there was a scuffle, and Ian got stabbed. And then the bad guys returned, and killed Ian. I think YY was supposed to be killed too, but she woke up in time and ran away. Why Bucket Hat left her at the bottom of the hill is beyond me.

In the end, I think Maestro Nam's crime will turn out to be that he stayed silent about what he knew. Maybe he'll get a chance to put things right by really saving Jang DH and YY this time.

I also have to say I was glad to see Papa Jang reveal that he was helpless to get justice for his son last year, but he's determined to take revenge for him now. Not that I think that's what Ian would have wanted, but I'm glad to see him reveal that he really did care for his son and was horrified by his brutal death.

If I hear one more time ‘what happened that day’ or ‘who killed Kim Ian’ am going to go berserk. Am glad the baddie died. He really wasn’t doing anything other than going to each person and try to be creepy.
This is a great ‘whodunit’ if it had been 12 episodes. The length is working against it.

Also am sad they forgot about our female leads musical career. Is she still practicing with the timpanist? It’s sad that everyone involved in this is going about doing their music while she is just watching from the sidelines. Now that she knows she is not the killer I hope she can come out of the guilt and try to live a little bit.

And for once we have a supporting family for the female lead. No orphan, abusive or jealous cousin, etc. that’s my favorite part of this show.

Haven't watched these episodes yet, so I'm totally behind, but I just wanted to say that I still don't understand this drama or think it's a very good drama or feel compelled to stay totally caught up with it, but I'm not feeling the need to drop it either and it's still giving me an odd sense of enjoyment it even though it's so flawed it feels like looking through holes in a slice of swiss cheese, lol. Sooooo, thanks for that, drama, lol?

*uhm so I was kinda warming up to bucket hat* *oops?*

Gosh how can a plot move forward and yet feels like it didn't move at all? I imagine that's what watching a snail move feels like.

Where does go charming Yoon? It was the most fun part of this show.

The "investigation" never interested me... The FL being completely stupid doesn't really help the plot. At least, she could be a musician, but no...she didn't play her instrument for a long time now.

BEWARE OF RAMPANT SPECULATION!

Part 1 of 3

Thank you for your wee-cap for episodes 21-24 of LET ME HEAR YOUR SONG, @missvictrix.

I thoroughly enjoyed hearing Jang Yoon’s performance at the inaugural concert. I recognize the melody he played, but don’t know its name. It sounds like a piece by one of the Russian Romantic composers, but that’s all I can guess. @ally-le, do you know what it is? It starts at about the 1:00 mark of Ep. 12/23. Thanks for your help. <3

One thing that stands out in my mind about Yoon Young-gil aka Bucket Hat Baddie is that Elton John’s “Good-bye Yellow Brick Road” is his mother’s favorite song. It makes me wonder if she is in a nursing home somewhere, and he has been desperate to pay her bills.

When we got that look inside Maestro Nam’s desk drawer that revealed the switchblade knife seen in earlier episodes, there was something else that Yi-young apparently overlooked: a long, narrow tan box that looked like a presentation box for a fancy writing instrument. How much do you want to bet that it contains Ian’s recorder fountain pen that he swapped with Maestro’s? I have a feeling that all is not lost when it comes to learning what was so incriminating it cost at least two people their lives.

About those pens: were all of them equipped with recorders? Who made the decision? Or was only this one retrofitted with the spy recorder? It wouldn’t surprise me if Professor Kang had something to do with it.

Whatever happened to the bouquet of flowers that Yoon Young-gil brought to Maestro Nam’s office? I know that I saw a view of it when Yi-young picked it up off the floor and put it on the desk that showed the note card stating it was from Yoon Young-gil. He said he’d leave her a “present” in case anything happened to him. I bet that note card is it, or a pointer to the location of “it.” It would be too much to expect the pen to be hidden in the bunch of flowers. Or would it?

I half-expect to find out that Yoon Young-gil left an incriminating piece of evidence in the album cover of “Goodbye Yellow Brick Road.” Yi-young was just about to ask the music cafe’s proprietor about his regular customer when the detectives came in to question him about the same thing.

- Continued -

Yoon Young-gil's bouquet of flowers that he brought to Maestro Nam's office before they met backstage prior to the inaugural concert contained yellow and pink roses.

yellow roses = jealousy
pink roses = happiness or lovers.
