Reason: The role of a soldier and the writers are 100% too burdensome
-It's too bad it's not Gongyoo, but it's a relief Song Joongki plays it.
-Song Joongki really fits the roleㅠㅠㅠㅠSo coolㅠㅠㅠㅠ I love youㅠㅠㅠㅠ
-But still, Yoo Sijin is Song Joongki..
-I think Gongyoo would fit the role as well..
-I like them allㅠㅠㅠㅠ
-They would have their own versions of Yoo Sijin, but still Song Joongkiㅠㅠㅠㅠ
-Kim Soohyun also would fit the role, in my opinion.
