The show isn't out but from the description they sound similar. The male lead cant interact with the opposite gender..its similar to how jiang zhi hao cant interact with ppl. Tho jang zhi hao opened up to the fml because she was persistent while the ml in about is love opened up (??) to the fml because he is immune to her
Both female lead is a vampire who falls in love with a human male lead. Both show the vampire family members and friends (second male lead) of the female lead and in ICHY, the vampire clan has evolved that they no longer drink blood but gained energy through human contact. However in ICHY, the male lead is a germophobe (dislike human contact) and in OM, the male lead hates vampire.
