Anyone who has been following SuJu for years are able to know who his favorite Dongsaeng is ~

If not, here are some hints:

He's part of the younger half of the group

His age is forever "B"

He should be living in the sea

He's in Two Sub-Units

Part of the most famous ship in SuJu

He's afraid of being alone, even needing company while eating

Only he and TVXQ's Yunho are allowed to speak informal to Heechul

Younger members feel like his hyung when they're alone with him

He wanted to get married at the age of 32, in exactly one year

He wanted to become an athlete, but changed his mind because of his father

He usually is the victim of being bullied by the members 

Any clue?

Who do you think?

Answer:

Uri Donghae!

The newest episode of "SJ Returns", Donghae did something to Heechul and escaped alive

If anyone else had dared to kick Heechul like Donghae did, I'm sure they'd dissapear without any clues left

They also kept mocking him that he wasn't that well known, our poor nemo ╥﹏╥

But in the end, he has always been Heechul's favorite dongsaeng, and here you have some beautiful moments of them together, enjoy!
