i think im one of the few people that honestly dont mind the whole "going from ugly to beautiful via the use of powers" theme. i mean, i would prefer the mc stayed the way he did, since his looks were one of the main conflicts he had in his life...if anything, the author should've held off on doing this sorta thing for atleast 20+ chapters before making the mc suddenly become hot.
i can see why people dont like this sort of stuff, but im personally ok with it.
