Nah. Yes, this ios i fact more gore-y and cruel, but in this case, Mujin never showed any sort of physical abuse towards Cho-ah, and it seemes like he really love him (eek, way too much lol) he takes care of him and all that which is sorta not Seungho's case.
ugh,,, mujin and choah is like another version of nakyum and seungho smh but this is even crueler
