Donghae has been promoting with Super Junior-M in Taiwan. Back in Korea, his best friend has been checking up on Donghae and has been asking how Donghae has been. Donghae's best friend would ask Donghae how his day has been and would tell Donghae that his friend misses him a lot. Donghae really misses his best friend too.

Donghae hates promoting in Taiwan and leave his best friend back in Korea. He doesn't hate promoting in Taiwan, it's just that he hates leaving his best friend behind. Donghae misses him too much. He misses him and yet he doesn't want to return to Korea. He doesn't want to return to Korea and see his best friend that would never love him the same way Donghae loves him. Donghae knows that his feelings for his best friend are unacceptable.

(A/N: Note that this is before Eunhyuk and Sungmin joined Suju-M)
