Remember at the start,e they said he was a tiger god reborn or something along those lines. He's not human, but pretty sure that panel was just like a metaphor not his mouth actually changing
I was also wondering about his teeth changing. Is the princess an omega? Why the fascination?
Its most likely a representation of the 'beast' aka tiger inside of him
Ah! got it. Thank you :0(๑•ㅂ•)و✧
So is he supernatural or was that teeth thing a metaphor for his ruthless nature
