CASSIAN
just finished highschool (18), went into culinary school (+2), army honorary discharge (+3[min]), webnovel&gamble(+x) total is 23+x year old. no matter how you look at it logically, there's no way he could be 22 after being discharged much less after webnovel and gambling arc. P.S. I said LOGICALLY. Don't freaking say x=-1
