Basically, an enjoyable movie, where the characters are sometimes likable and sometimes immature. You know every person grows, some with time and some in the blink of a moment.
Showing up an ugly truth of the society where a pregnant teen or a woman is always a female fault. Like why is it a fault, it happens due to two individuals, so why only the female is to blame.
You cannot adopt a child if you are single, but you cannot get an abortion if you are underage. Why give the responsibility of raising a kid to a teen than to have an abortion. She has just begun her life. Because this society is run by the rules of adults.

I love Kim Hyun Soo, though I have seen her in various movies, but recognized her since The Penthouse series. She had a way to make her character come to life. She lives up to the expectation so well. She was a mature teen but still had the charm of adolescence who makes mistakes, embraces mistakes, and struggles to find a space in the harsh society.

Kim Hye Soo was nice, showing the exploited character of a diva, who is an immature adult and selfish. She deserved all the hate throughout but claimed her share of claps in the end when she actually did something against her usual self.
I hated the sister who was selfish and duped her in that status. she was the real selfish.
One should definitely watch this movie to see the different approaches/ views of adults towards teen pregnancy. the family, the school, the friends, neighbors, strangers, and the FATHER OF THE KID.
