Is Sangmin Dinneaw coming back?

When he was a kid, Sang Min spent time as an exchange student in Thailand where he stayed with Orn, the mother of Dinneaw who was very young at the time. More than ten years have passed with Sang Min back in Korea. The whole time, he didn't stay in contact with the family, until one day, Sang Min has reason to return to Thailand and stays with Orn once more. There, he reencounters Dinneaw who's grown up to be quite handsome.
