Wait I totally forgot about that too!!
When did that happen? Do you know the chapter? I'll like to revisit to refresh my memory
Oh shit (⊙…⊙ ) I forgot about that (╯°Д °)╯╧╧
i can't recall the specific chapter but i think it was a little after they visited the orphanage. it was when yigon was feeling anxious then he went to the restaurant(?) that taekang had his meeting.
The bug was in one of Yigon's coat, surely it went through a washing machine since then.
hopefully.
i'm still anxious by the fact that taekang's unit is bugged and they haven't figured it out yet!
