A Relationship as Thick as Blood

Synopsis

"The day after I slept with you, I... can't get an erection."

College student Park Ha-Min is a self-made nerd who wants to be present and absent among his peers. The reason Ha-Min is sensitive to his own presence is because he is actually a vampire who hides his identity! Ha-Min, who attended the opening ceremony against his will, naturally gets noticed by Ryu Tae-Ha, the most popular person in the department... Ha-Min, who continued to drink to enjoy the uncomfortable situation as much as possible, eventually gets drunk. Ha-Min, who couldn't come to his senses due to the alcohol, opens his eyes in... a motel! Tae-Ha, who is talking nonsense next to him, panics and decides to distance himself from Tae-Ha...

"I told you I can't get an erection because of you?!"

Tae-Ha, who was bitten by Ha-Min right before having sex with him, demands that Ha-Min take responsibility, saying that he has erectile dysfunction since then! The biggest crisis in his life as a nerd vampire! Will Ha-Min be able to overcome it?
