My Big Brother's XX is Such a Worry!

'''Introduction to the Work: It shares the same worldview as 『Big Brother's XX is in Grave Danger!』. Last summer, due to an incident that occurred on his ex-girlfriend's birthday, Kim Hyung-nim, who had been suffering from erectile dysfunction after secretly receiving a psychological shock. After agonizing over this matter in secret, one day he suddenly finds himself in the opposite condition: persistent erection. The eyes of the various doctors around him who happen to learn of Big Brother's condition seem a little suspicious?! "I am a doctor, you know. Hyung-nim." Just trust me. I'll fix everything for you.'''
