Age difference did change because they aged him up??? Isagi WAS 16 and only later did they change his age to 17. But to be fair kaneshiro never made any sense with the ages because in the early episodes they said isagi was 17 despite it not matching the timeline, then changed him to 16 (according to the egoist bible) and then changed him back to 17 since it made more sense. I do not care about the exact difference between their current age difference since i have long stopped caring about blue lock and anything related to kaiser, my comment was posted over a year ago, i do not see why you thought it'd be a great move to insult someone over a comment they had long forgotten and stopped caring about. Enjoy your kaisagi ship or whatever you like, it is not my concern.

Kaisagi is the hottest ship in Blue Lock idc talk to a wall, and people who click (while obv knowing what ship it is just to hate) are the worst breed of persons ever.
Kaiser being the absolute tease to Isagi will always make me feel something ლ(´ڡ`ლ) and the after-care clearly shows how much he does care for Isagi ♡
