You, Lim Jukyung, a new student in Saebom High school, you like this popular guy named Soo-ho, and you didn't know he likes you too. But there's this guy named Seo Jun really likes you. But this girl, your friend Kangsu likes Soo-ho, and they're childhood best friends so you thought that Soo-ho likes Kangsu because of their closeness.
Now there's a school trip, and there's a game a paper you and your team will step on it and try to balance your selves, you were almost in Soo-ho's team but Kangsu joined, so you're alone thankfully Seo Jun never forget about you and pull you to his team.
Now, as the game goes on, they need to fold it quarter size, and now the two of the team needs to carry one of them.
Seo Jun didn't lose any chance, he scoop you to his arm in a bridal style
Soo-ho saw that and couldn't control him self to go towards you two, but his friend pulled him back, he doesn't have any choice so he just carry Kangsu too.
But deep inside, he really wants you in his arms..not Seo Jun's. As the game goes on Kangsu and Soo-ho win, but he wasn't happy, while you and Seo Jun is just ok that you two loose, and Soo-ho couldn't stop looking at you two, the jealousy is taking over him, and the way you avoid him is killing him.
