Imma just make a theory that he gets so surprised that he somehow starts moving (by like shaking Takamada or something) and he's gonna drop the keys ┗( T﹏T )┛ Let's see how this goes
So, I'm just gonna leave my theory that Sooho is like probably an angel (or like half angel) here, even though it's most likely wrong because that's kinda the main idea of the story (for him to be human) but whatever ╮( ̄▽ ̄)╭
Time to waste my money ╥﹏╥
