serendipity

I am not referring to you directly but to a lot of people saying that NJH is not suitable for being the male lead cuz he is shy and timid and lacks self confidence

I never disagreed with that, he has his own plus points and a unique charm but majority of his character traits are not new in male leads.

Reading all these comments about how Jipyeong deserves to be the ML and there is one point I need to highlight. (this might be offensive) His character is literally the stereotyped MLs of dramas except here he is the second ML. People go on about how kdramas need to move away from stereotypes and need to start introducing elements that are different and not much used. Dosan is a character that is so uncommon as the ML in kdramas and brings about a refreshing change. If you guys have so many problems, seeing someone who is more on the soft and emotional side of the spectrum, there are a ton of other dramas that will suit your tastes.
P. S The point of this plot is not just the romance and there is a lot to uncover with the growth of Samsan, the rivalry and the past of the sisters, and the individual growth of the characters.

I think the characterisation of the show is done very smartly. They gave us one fully-fledged character with his background and his development from his childhood as since he is already successful in terms of career, there is not much for him that we can continue to see. Whereas, Dalmi, Dosan and Injae are very hidden characters who continue to struggle and face obstacles as only with the latest episodes we are given a chance to peek into their journey. With the most recent episode, we are given a look into Dosan's formation of the company and I am sure we would start getting an insight into Dalmi and Injae too.
So having Jipyeong's characterisation with the past would balance out the development and the growth that we would see from the rest of the characters in the present

I think the biggest problem with her character right now is that we have no insight to her background and growth, we didnt get any chance to connect with her character. With the recent episodes, we started getting a tiny peek, i hope that changes soon and we start recognising her struggles and her pain too

Sandbox is just a start up accelerator, it helps them gain investors and helps people who lack resources to join one. The hackathon wasn't something that was easy, it was a competition between 200 people for only 25 people to get selected.
Judging from the preview, they have only 6 months to try and get their company to start functioning and working, after which they should be able to manage everything on their own(?)

there are several theories of it being Yongsan or the developer in Injae's team

i agree, i am surprised people havent been calling that out. he keeps looking at the grandma as someone who he owes a debt to

by the debt i meant whenever he talks to the grandma, there is a continuous mention of how much he owes her and how much he needs to pay back

I think what she meant was, did you help Dosan because you liked me

Another interesting analogy I read, this is not my work, I am just putting it out here for y'all to read.
The spoiled milk was a metaphor for the white lies that grandma and jipyeong made for dalmi. also, it's foreshadowing the time when the lies will all be revealed and it will be like how the milk bottle exploded resulting in Cheolsan losing his vision(in this case it would be the grandma). The one who knows that the 'milk' will definitely burst is the most important person, which is dosan (the key man in this ep), he's the only one who knows all of the secrets.
Hence the lightning too which would lead for the milk to get spoilt, as in the big event that would lead to the lie coming out

thank you so much!

For everyone with the SLS who is only going on about how good Jipyeong is and how much he deserves the world, I agree (well just a tiny bit) but that is not the point of the story and neither is the romance.
The title is titled Start-Ups and the entire plot is going to revolve around that. Now that we have reached episode 6, all the characters have taken their first step and now evidently the story will start to deviate from their personal lives to their professional lives. They are going to be working hard to find investors and doing whatever they can to make sure that their company doesn't sink, all the more while battling whatever obstacles that stand in their way. It is an interesting plot even without the romance and do not downgrade it just because the romance is not to your tastes.

Second, the lies and the misunderstandings, (young) Dosan (in the letters) was a role model to Dalmi and she looked at him as her source of comfort. Did she ever express that she wanted to meet him prior to playing that bluff, nope, she was living her own life and had her own struggles to worry about. Dosan was just a benchmark that she had set for the bare minimum in her standard of guys. Now that she met Dosan, on the bench she said, "I am curious and I want to know everything about you", she acknowledges that they haven't met for 15 years and they aren't the supreme part in each other's life. She was willing to accept he had a gf but the idea that he didn't just made her happy. Her true glee that day was from shutting her sister up and proving her wrong and not from actually meeting the guy behind the letters.
Dosan was the guy who provided her support in her childhood and she looked for someone who can do the same thing as an adult. Mind you she hadn't even told Dosan about entering Sandbox and making such a big decision in life

Third, this might infuriate a lot of people out there but this is my perspective, the grandmother and Jipyeong have a very wholesome bond and it is beautiful but the idea of debt in between it ruins it. The grandmother doesn't care about the debt and how much she did to help Jipyeong but for him he keeps looking back at it as if it was debt. I am waiting for his understanding that sometimes in love, it is okay to sacrifice and the grandmother did exactly that. She treated him like her own and will continue to do this.
On the same note, Dalmi and the grandmother are very attached too, I read some comments about how anything happening to the grandmother would wreck Jipyeong but would okay to Dalmi(?). That lady is her grandmother, the one who stayed by her side for the past 10 years when everyone around her left. They ate, smiled, cried, laughed, shared worries, worked alongside each other. Potentially anything happening to the grandmother would completely wreck Dalmi.

Lastly, for the lie stretching out too much, it is reality. Life doesn't wait for one obstacle to get over before throwing the next and it is precisely that. She doesn't need to know the truth before her next hurdle is thrown at her. as the grandmother said, she is a cosmos flower and she will bloom just not with everyone.
Saying this with the idea that I already believe that Dalmi knows the truth that Dosan isn't the actual guy behind the letters. There are several things that happened including the birthday on the shareholder sheet, her asking him whether he had anything to tell her, the handwriting, the way she confronted Jipyeong and lastly, the way she kept confirming for his support in Samsan.

Does anyone here think that Dalmi might already know the truth? she might have several opportunities to have known and the way she confronted Han Ji Pyeong, makes me believe that can be true.
Another opportunity for her to find out that he was lying was the birthdays, it was evidently mentioned on the stakeholder list and then when walking home that night, she asks him whether he had anything to say to her

On that note, this episode was a filler... it only had comical relief and the setting of the company to set the plot of the future episodes. I am really disappointed knowing that 5 episodes were wasted into the romance when it isn't even the main focus and then the next episode is required to fill up for the actual plot.

I might be rude for saying this but I don't think the letter misunderstanding would change much for Dalmi. Moreover, the letters were a source of comfort for her 15 years ago and not once did she think of finding him unless it came to her sister and their bluff. They were pen pals for a year, they ended their contact and then both of them had their own lives to focus on, The only reason she needed him back in his life was for the bluff she had used and the punishment for using the "Nam Dosan" as her boyfriend. The same thing applies to Han Ji Pyeong and the grandmother, they were paying the price of using that name in their letters.

The narration is not from any character's POV here so we don't even know whether she knows the truth yet or not. I am more excited about the mysteries and the revenge plot over the romance and the letters, it was hyped way too much in the previous episodes

no, this isnt pre produced, shooting is still ongoing.
Dosan is just more subtle and different than the usual male leads. He is a complex character with a lot of layers still discovering and learning. I am sure the plot has a lot more than the love line right now, following the latest episode

this show is not as simple as it seems, the entire misunderstanding, the letters and the lies, the epilogue of ep 6, each and every single element has been carefully thought of and plotted. tbh, I don't think Dalmi would worry too much about the letters, she might be shaken or would be angry as to why they lied but nothing more. It would be the rest that would take a heavy toll on her

I can probably edit the comment to make it comprehensible but when i said closeness, I meant Jipyeong is scared of seeing Dalmi being hurt when he saw that they are working together and all...Just in case, the truth ever leaks,

When i meant closeness, I didn't mean jealousy... based on your comment, i am assuming that is how you are interpreting mine.
