Chapter 15: HUWOOOOOW NEW STORY

Chapter 14: Disini boleh gak yah komen pake bahasa Indonesia? Soalnya bahasa Inggris saya pas2an Thor...author orang Indonesia kan? Gapapa ya kalo saya pake bahasa Indonesia? Huftt...masih nyesek nie. Mau ngungkapin segala sesak didada(?) selama baca ff ini tapi bingung mau ketik apa? Hehe. Yg jelas makasih Author uda buat saya mewek n mata bengkak dihampir tiap chapter-nya. Bener2 jago deh bikin nyesek pembaca, dua jempol buat plot-nya. Kurangnya cuma di typo aja sih yg paling ketara, banyak kata yg seharusnya HE tapi diketik SHE ato sebaliknya SHE jadi HE, Brother jadi Sister (chapter 5). Sayang bgt jadi rada keganggu bacanya tapi overall KEREN ff-nya. Jujur saya ngarepnya jadi Romance OngNiel-nya ( #OngNielShipper hehe) tapi gapapa, bromance juga bagus ceritanya. Ahh saya kebanyakan ngoceh...sekali lg makasih Author uda sedikit 'bantu' saya mikir ttg hidup saya ;)

Chapter 14: YEAYY FINALLY THEY MEET...IT THE BEST ENDING WHEN EVERYBODY DINNER TOGETHER AT THE ROOFTOP

You actually made me Cry ..I cried like I found my own long lost brother..u r too good at making people cry ????..I loved this fic..I completed this in 3days.. anyways Happy New Year Author-nim

Chapter 14: Ahh, I love the fluffy ending —although I expected a full blast angst based from the MV since I'm a pathetic masochist who will then bugs with "why" all the time but okay whatever forget it— I honestly thought the story would be longer. Daniel will wait for Seongwoo and the latter letting him go with his heart but this ending is good too. I was as shocked as Seongwoo when Daniel appeared in front of him.

I like Kuanlin's introduction here. He's the same as the 'sweet guy' in real life (and I love the joke Seongwoo made regarding his heart is as handsome as his face lmao) Although, the other characters —the Wanna One members I mean— are mentioned very brief and I would likely be bitter about it, I think it's fine since it's like that too in the MV. Nu'est appearance are also as acceptable. They're older so they fit well as employees at the company. Frankly, I don't understand the need of Giae, an OC in this fic since it already has numerous of characters. If she is created for advising Daniel, I think any of Daniel's close friends can do that —preferably Jisung or Jaehwan since they know Daniel's backstory and would suit very well for said dialogues— but she never interrupted any scenes or spoil the plot or a turnoff or whatsoever so yeah. She's all right.

The plot overall is great. The way you express the characters' emotions & describe each scenes are good. I'm satisfied with the story & the ending.

Grammatical errors can still be spotted but your vocabulary is good. Misspelling is also visible here and there (I assume they're mistyped words instead of misspelled) but as I said, it doesn't ruin the story at all. So don't worry too much (but it's better if you take a look at them once you have the time and do some tweaks to the typo words) Also, I suggest you change the title from "HEARTSTRING" to "Heart Strings" nothing drastic actually, just the change of the capital letters and a space sot would look decent (not that the caps lock isn't, it just doesn't look right or captivating much)

You're very potential to be an excellent author. Don't give up & keep going on, okay? You've done a great job for this. I apologize if my comment offends you (some say I'm too blunt on criticizing/reviewing/commenting on fanfics) and taking a large space at the comment section. I'm always like this when it comes to fics I approve lmao. I like your poster too. Little Daniel & Seongwoo are very cute (did you watch the kids' audition on Wanna One Go? It was very impressive)

Okay, so I gotta stop talking now. Thank you for sharing this with all of us. We appreciate it very much. Keep on going forward :)
