Getting rejected once is unfortunate, but getting rejected three times by three separate guys is a phenomenon that requires careful studying. For Seong Jin, love was supposed to be simpler, especially once he stopped seeing boys as awkward, tinier people and had this sudden want to date them. But secondary school romance proves harder than expected. And after a trio of crushing rejections, he swears off feelings entirely. Until it happens again. Another unrequited crush sneaks up on him, and the only place he can vent about it is through his chaotic vlogs. What he never expected was his memory card falling into the hands of one of his old crushes... who is now blackmailing him with footage that was never meant to go public.

When 17-year-old Jamie leaves a letter in an abandoned forest mailbox as a joke, he doesn't expect anyone to reply-especially not Elliot, a boy claiming to be a ghost who died in 1987. As the letters pile up, so do the mysteries: Who was Elliot, really? Why is he still here? And why is Jamie starting to fall for someone he might never meet? But the closer Jamie gets to the truth, the more he realizes that Elliot's story-and Jamie's own-are connected in ways that defy time, grief, and even death.
