https://kisskh.at/5984-advertising-genius-lee-tae-baek - This is 7 years old, not the best drama in general but I really liked the advertising parts in the drama. As a person with media assistant degree I found this really interesting when I graduated 7 years ago. Now studying marketing and I still remember liking this one.
https://kisskh.at/4412-rich-man-poor-woman - I would also recommend this, especially if you are into IT & application/website designing as it has that aspect quite strong. It has some romance but I recommend it for the IT part at least.
// EDIT: I'm also from Finland :D
Oh jesus, based on your insta we're in the same school too. What the christ.
Thanks for the recommendations though lol.
