Comment by Leeyii on Checkmate (TAN) - Episode.. : special episode

@Leeyii  but there's smth weird I mean if he's 30 and Blondie is 29 even if he's born the 12th January it technically means that they're not born the same year even though they were in the same class and I doubt that our mc retook a class 🤨🤨🤨

@Username  People with birthdays on the first 5 months usually skip a year (most likely grade/year 0 or 1), Eunsung is 29 but his birthday January so he most likely skipped a year.
