I gave it an 8. Honestly, maybe it doesn't deserve that high but I gave it because of Jipyeong and the theme.
In terms of character wise, single-handedly saved the drama. He is the male lead for me even though he didn't get the girl. His storyline was the most interesting and developed and his relationship with the grandma was heartwarming. I did love the Samsan tech group and their chemistry but not the main CP. The story actually didn't give Jipyeong a chance to pursue Dal Mi at all. Initially, he had to pretend so he kept the distance and not too long after his confession, the time jump happened, it seems like he still kept the distance.. they just didn't give him the chance to get close to her. Didn't like the fact that they tried to keep us guessing almost until the end.
Other than that romance part, I think it was still enjoyable. The theme about start-ups and incubators and investments were interesting. The friendship between the three guys was great!
I would suggest try watching a few episodes. If you like Jipyeong and don't mind shipping the wrong CP, you should be able to enjoy the drama!!
