Jinyoung is a player and a flirt with his looks and beautiful voice. He can charm just about any girl with just a few sweet words.

Yugyeom is the opposite of Jinyoung. Polite, quiet and reserved. Although he has the looks he doesn't realise it.

Areum has been battling feelings for both of them for years. Jinyoung played with her feelings but she also had been crushing on Yugyeom since they were young.

This summer she had finally decided to move on, to distance herself from guys and just have good fun with her best friend. It was her last year of college next year, she would be graduating, finding a job and starting her new life. She wanted to leave old, naive, lovestruck Areum behind.

However, life doesn't always go the way it's planned.

Jinyoung's parents planned a summer getaway at their family beach house for Areum, Jinyoung, Yugyeom and friends as a surprise before they finish their last year of study. Although Areum couldn't think of anything worse, she couldn't turn down such a sweet surprise.

Her plan was to stay away from those boys and now she was going to see them everyday. Luckily her cousin, Baekhyun would be there but he secretly invited his own group of friends. How could she possibly handle this? It would be hard for any girl to move on with shirtless guys always walking around.

Though this summer, Jinyoung started to behave differently around Areum. He started to become more sweet and less playful and more sincere. Yugyeom started to become a bit more outspoken causing him and Areum to get closer.

She is supposed to be moving on but why does she feel more confused then ever?

Will Jinyoung change and stop being a player? Will getting closer to Yugyeom lead to anything?

Or will Areum finally move on and stop living in an emotional rollercoaster.
