If you lived through—or are still living through—high school, you can relate to Joon-Woo. An outcast and a loner, his only joy comes from the hours he spends on his phone, randomly chatting with strangers. It's all weird and meaningless, until Joon-Woo strikes gold—as he's matched in a private chat with a pretty young girl his age. Jackpot! But when he discovers that this same pretty girl is actually his classmate Seung Ah, things get a little too real for a guy who's never even remotely been kissed. (Source: Webtoon Entertainment)
