Extraordinary First Love

Synopsis

In a world where humans and beasts live together, one day, the main character's childhood friend, Beom, appears as a beast.

The treatment method to prevent anthropomorphism is human saliva that has not been in contact with air, that is, kissing. He doesn't want to see Beom, whom he's liked for a long time, kissing another person, so he's out of breath and goes out to act as a treatment partner...!
