Great k-drama. First of all the visuals. This kind of nostalgia in the photography perfectually suits the 20-21 years old protagonists. An era when everything is possibile and you are still experiencing the first love, first job, you think what you gonna do with your life etc. A style similar to "Video Games" by Lana del Rey or "Hurt" by New Jeans videos. Simply amazing.

Then Doona. Doona is the kind of crazy girl no man can avoid to fall in love with. She's just amazing. Funny, sexy, smart and talented. It's sad also when you realize that this firework girl is taking you away from the "wife style " girl you always liked, but you cannot do anything about it. The last episodes lose a little bit of spark and become more cliché. The end should have been clear about the fact that the relationship ended, as it should have been in the reality. Instead it seems they still meet each other which is highly unrealistic. If you are a normal guy, engineering student, Doona can only be the love story of your youth, the one you think about when you go watching your son football game on sundays.

Doona is made to be a star, Won-jun helped her find herself again in a time of crisis. In the end she is sad because he disappeared when she started to be ok. But disappearing is the only thing Won-jun could do after Doona recovered, as she is made to shine alone in the life.
