Some k-drama stars are really good at rewarding their parents for the love and support they received during the formative years.

Won Bin is a good example. Won, who recently married actress Lee Na Young, bought his parents mansion as a gift. He was ranked top of the list of celebrities most devoted to their parents on the June 15th episode of the Korean news show, "The List 2015." Won Bin has said that when he was young his parents worked from morning to night, without eating well or ever having a vacation. They had a tough life raising five children. He bought the mansion as a reward for their efforts in 2008 and the customized design won an award at the 2008 Korean Architecture Awards.

But he's not the only k-drama actor to buy a home or a business for his parents. In 2013 Infinite's Hoya gifted his parents with a new home.

"I bought a house on Parent's Day this year," he said when he appeared on the program "KBS Happy Sunday Mamma Mia."

The singer-actor currently plays Soo Ae's concerned kid brother on the melodrama "Mask."

Singer-actor Kim Hyun Joong, last seen in "Inspiring Generation," rewarded his parents by buying them both a home and a business. He purchased them a high-end residential building worth $800,000 and a Jaksal fried chicken restaurant, where he has on occasion been seen washing dishes.

Park Shin Hye bought her parents a restaurant from her savings 10 years ago. And she continues to help promote the restaurant and support them. She not only takes celebrity friends such as actor Yoo Yeon Suk, Jang Geun Suk and Lee Seung Gi, to her parents' restaurant, but she works there when they go on vacation. She once ran the restaurant for a week while they were gone. She waited on tables and even grilled the lamb dishes that are served there. And the actress, last seen in the film "Royal Tailor" and the drama "Pinocchio," has been known to prepare special birthday meals for her family.

Seo In Guk, soon to be seen in the drama "I Remember You" with Jang Na Ra, set up a coffee shop for his parents. When he appeared on the KBS talk show "Happy Together" he spoke about his hardworking mother and his gift to her.

"I think it was the best thing I have done all my life."
