Like other devils of his kind, Hyeonshin has adapted to the modern world to consume the Deadly Sin, Pride. Working as a plastic surgeon means there's always more than enough ego around him to feed off of. There's just one small problem: because of past trauma, he has an overwhelming repulsion toward blood! Luckily, a solution appears in the form of a plucky human named Ina, whose eyes seem to have the mysterious effect of alleviating this condition. Knowing that she's desperate to book a surgery at his busy clinic, Hyeonshin agrees to operate on her if she helps him with his "blood tolerance experiments." But due to their clashing personalities and constant interruptions from his devil coworkers, Hyeonshin's recovery seems far away. Will the devil and human both be able to attain what they truly desire? ⓒ sun_ah, jayang, Ante 2022 All rights reserved. Published by Tappytoon under license from partners.
