Bc Eunsan's birthday is on August 6th so 8 as in the month of August and 6 bc of the dateHope my explanation made sense lol Soou
Eunsan's birthday is on December 21st, that's why he has a 21 on his jersey. They met on August 6th which is shown in the earlier chapter when Ian uses his phone to check the time.
Can someone explain why he chose 86? (August 6th)
