When we see Heonjae imagine Myeong-IL as the CPR dummy I can't tell if it's because he just wants to kiss Myeong-IL or if it's foreshadowing that Heonjae will try to do to Myeong-IL what he did to Mr. Kang. I wouldn't put it past him since he literally said that he wanted to cut some Myeong-IL's skin.
