I watched Catch the Ghost first, so I noticed a lot of thing when I watched Startup. It seems that PD Oh like to incorporated many Go Jiseok scenes into Han Jipyeong, if possible.
1st one I noticed:
Kim Seonho's hair should be wet with towel in his neck

Next: Kim Seonho should be hiding under the desk and doing hush sign with his finger

Kim Seonho always look hot as Go Ji Seok in tshirt, so let's create circumstances where always suit up Han Jipyeong wear only tshirt

We also want Han Jipyeong with umbrella
P.s but he wont get the girl so the scene will be halmoni

Go Ji Seok did so much running scenes. But the most memorable when he run for his love ones. Let's also do it for Han Jipyeong

Go jiseok is awesome in fighting scenes, still hot with beaten up face. Let's make han jipyeong get into a fight

Go Jiseok practiced confession was funny. We should make Han Jipyeong do it too, just change flower bouquet with jewelry
P.s: even though he's 2nd male lead.

Oh we need awkward tense elevator scenes with argument

Go Jiseok heartbreaking cry in the car scenes was amazing, let's do it for Han Jipyeong but make it expensive

Offcourse the highlight: emotional acting showdown with veteran actress. Mom vs Halmoni

Too many recycling scenes make me believe that:
1. PD Oh did whipped for Kim Seonho & he utilized all of Kim Seonho capabilities to the max.
2. Recycling scenes made me felt SU's lost its creativity. KSH's acting: different potrayal between Jiseok & Jipyeong save the show for me.
