Boy-Friend's Rule

High school sophomore Kim Jiun believes in love at first sight—and the most recent object of her affections is the gentle and dashing Choi Jae-i. Just as the introverted Jiun musters up the courage to confess her feelings to Jae-i, he reveals that he has had a years-long crush on a girl from middle school. Somehow, Jae-i ends up mistakenly believing that the person Jiun likes is his rather reserved best friend, Lee Seohyeon.

As Jae-i attempts to play matchmaker for his two friends, Jiun properly thinks about Seohyeon for the first time. He has always remained at the edge of her interactions with Jae-i, and the few times they were left alone, she struggled to understand his dry-wit humor and indifferent attitude. But Jiun now notices his quiet thoughtfulness and the rare warmth of his smile, wondering if the love she has been searching for has been right in front of her all along.
