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? (Source: Lezhin US, edited) Note: The chapter count includes 2 side stories.
