Donghae have this slight problem when travelling – he can’t bring himself to easily fall asleep. It took a long time for him to get used to sleeping the dormitory and now that he's part of the sub-group SJ-M, he took a deep sigh... it was another environment he has to get used to. If only his busy schedule will help him fall asleep fast, unfortunately, even with his schedule he still has insomniac episodes...
