Playful Kiss is based on the Japanese manga Mischievous Kiss. Brought to you by Group Eight (Goong and Boys over Flowers). The drama has previously been made for Japanese and Taiwanese audiences and they both were a huge success. Playful Kiss is about a popular and genius male student named Baek Seung-jo who has a stand-offish personality and Oh Hani who is a female student who makes up for being not-so-genius by always being smiling and happy. An earthquake destroys the girl's home and she and her dad end up living with the boy's family. The girl has kept this boy in her heart but she has never received any assurances of her love being reciprocated. Fun and groans ensue as they interact and rub off on each other.
Young British noble William hops on a Japan-bound ship to look for Far Eastern treasures, but he gets thrown overboard during a storm and drifts to the exotic island of Tamra. Despite the language barrier, he falls for local girl Beojin, a cute and inquisitive young lady who dreams of life elsewhere. However, Park Kyu, an arrogant, exiled noble, isn't going to let William take Beojin away without a fight. But most importantly, all their lives are at stake if the government officials find out there's a foreigner on the island. Add in a mysterious Japanese sailor from the East India Company and an iron-lady merchant planning an insurrection, and little old Tamra Island is suddenly overflowing with romance, mishap, and adventure!
