Jo Jung-suk, who played the older brother to EXO’s D.O. in the film “My Annoying Brother” and appeared as a merman in “The Legend of the Blue Sea,” is promoting English education.

Jo became the official face of Yanadoo, an English private education institute, in November.

Yanadoo’s Instagram account revealed model shots of the 36-year-old and a minute-long commercial clip, in which Jo makes full use of his cheeky charms as he throws the promotional lines like a playful older brother.

Heaving a sigh of exasperation, Jo begins, “Is your new year’s resolution mastering English conversation, too?”

“Are you good at English? Do you like studying? No, you aren’t, and no, you don’t. So don’t pain yourself studying the big words you will never use in real life,” Jo says, emphasizing the need to get comfortable speaking the foreign language by using simple vocabulary.
