Hmm yeah I can definitely see why you would! Especially with how Tia didn't stop acting like and adult as a 'kid', and Perez has always been a bit cold. I can see them as adults, mainly Perez because his growth mentally is more of a adjustment to a time skip over Tias, who again acted like a adult before.
I think it's because their personality as kids were already mature. So we feel that there was no difference.
Is it just me or maybe this is part of me adulting but in my eyes i still see them as little kids from earlier chapters
