Ms. Jennifer Hyunjong Shin
Jennifer & Haeyun lived together in college... They suffered together through the rough times at MIT. There were late-night studying, late-night talks, late-night snacks. Laughs and cries, shopping .. shopping .. shopping .. and lots of shoes!

Mr. Yong-Suk Kim
Yong-Suk & Tae-Sik have been buddies since they were freshmen at SNU. They share many things in common--mechanical engineering, love of basketball, KBL Apt. 128, and, before Tae-Sik met Haeyun, not-so-good luck with women.

Ms. Hyun-Jung Lee
Hyun-Jung is Tae-Sik's sister, and by extension, also Haeyun's sister. She is beautiful, smart, kind, and single. How can that be possible? What's even more hard to believe is, she's very nice to Haeyun, and they get along very well. :)

Mr. Hee-Jin Lee
Hee-Jin is also one of Tae-Sik's best buddies from college. Although he has a girl's name, he looks and is very manly (typical kyung-sang-do namja).
