I have the feeling the new guy is someone like an author or something, you know someone who has to meet deadlines and has no time to sleep or bath due to his hectic schedule.
I may be crazy but I can really imagine Hyesung and his baby crying together. Hyesung being seriously helpless when hes baby cant stop crying, cries with him since he has no idea what hes doing. Then Dojin catches the scene, completely speechless who to console first lol!
Ahhh I cant wait to see diablo!
