Seoul in the 1980s is an exciting place to be…that is, unless you’re Seong-Ho. His pushy father expects him to do nothing but study, so day in and out Seong-Ho buries himself in his books, oblivious to all the exciting new things happening in town. There’s one thing that’s been distracting him, though: these unidentifiable migraines that just won’t go away, no matter how many meds Seong-Ho takes. One day, after a particularly painful headache, he finds himself kissing a stranger. Horrified and appalled by his transgression, Seong-Ho immediately tries to erase that unfortunate happening from his memory. That would be the end of that, but…what if kissing is the only way to get rid of his migraines?
