no not them (kpop group named nct)
i never found negative canthal tilt to be all that unattractive, i guess only if its combined with other unattractive features it can drag the face down.
i dont understand why people find it unnattractive? is it an indicator of health? good hair and skin quality is attractive to us because it shows that that person is good to reproduce with, but what about negative canthal tilt? anne hathaway has it, some other good looking celebrities too, i dont understand.
