I read like 90 chapters , the ML gives off a saint vibe but deep within ofc he isn't, he is very calculating .. spoiler from what I read they aren't arch enemies actually , it's what FL thinks about them ... He is very kind and loving towards her , and he is a male wife material hehe , he spoils and indulge her even though he is more powerful than her and is greatest swordsman , she ranks second (which is why she hates him lol) , he loved her without asking for anything in return
