I didn't think about the drink, but you might be right.. I think maybe Hajoon will let Mieum go to see if he would save Jitae again (because the same scene happened 10 years ago, Jitae being attacked with a bottle), and wants to see Mieum get hurt again (phisically) and Jitae being in pain (mentally)

Why do i feel like he put something in his drink I may be tripping but he just want to see jitae suffer so much that he’d drug Mi-eum, and do something to him while he’s unconscious
