This drama has alot of Heart. 18yr old youthful heart to be exact. But despite its cheery title, it's also realistic and shows the plight of students who are struggling. It doesn't matter if they are rich or poor, privileged or not, overachiever or underachiever, they all face alot of personal problems that in some instances rob of the innocent friendships and playfulness of youth We have a budding romance between the sassy outspoken if rash Yeon Deol butting heads with Yeol the class president and the most intelligent boy in school. You have awesome bromance between Yeol and his childhood friend Ha Yoon. You have Yeon Deol and her fellow club friends. You have the friendship turn betrayal between Yeon Deol and Soo Ah who is the character everyone loves to hate until you see what drives her to those actions and in the end although I don't condone her actions, I do pity her and understand her plight to a certain extent. This drama is a little heavy in my book. Cause it is sad to see the youths being forced and even bullied by their parents to get top grades. The school is so competitive that the students have to view each other as rivals. And then there's the case of bullying and the case of Ha Yoon's abusive father which really makes me feel sick. Sigh let's say I usually like fluffy and sweet dramas and hate too much of these injustice xxx Back to the love side: Yeon deol 's character really grows on you. She has so much guts that if I'm a guy I would like her too. Yeol is the fast thinking guy who don't usually care for others except his best friend. Through Yeon deol he gained courage to trust in people. And through Yeol she learned to calm down and think before act. I like that he wasn't wishy washy when he realised he likes her. And true to this words, he doesn't beat around the Bush or hides it behind his ego like alot of male drama characters. I really like how the cheerleader club members slowly warm to each other and the friendship that develops. The competition itself isn't for winning. It's really about seeing things to the end, not giving up and doing something you love with your friends. It makes me think of the time I was 18. I also enjoy the good teacher characters. But the principal annoy the hell out of me. And Ha Yoon 's character is just so sad. I wish we can have a follow up drama for his story only. That's how much I like him (and Ji soo who portrayed him) All in all. I enjoyed it thoroughly but somehow I don't think il be re-watching it any time soon
