i think the flashbacks are kinda necessary to establish our characters more, and probably to distinguish the differences between ian and brian in the future. i mean yea they're long, but its quite evident that brian is very different from ian and that would probably be very important to the plot esp with the two dragons.
i just keep coming back to this manhwa like a toxic ex TT oh my god can he just leave my bby alone ╥﹏╥
