Childhood friends like family, but everyone thinks we're dating.
Oh Taeyoon and I have been childhood friends for over 10 years, seeing each other at our best and worst. We go to school together and even attend the same academy, so our classmates already call us an official couple. The thing is, we don't actually have feelings for each other. After school, the moment I return to the empty classroom to grab my bag, a giant heart drawn on the chalkboard with our names inside catches my eye. Taeyoon, who followed me in, lets out a hollow laugh as if the sight is absurd. As the kids' pranks get worse, my best friend Kwak Minchae relentlessly digs into our relationship, determined to find definitive evidence. Inside the classroom where chalk dust hangs in the air, will we be able to clear up this exhausting misunderstanding? Or has a strange tension actually begun to form between us?
18 A handsome boy with sharp features and a neat school uniform. He seems indifferent to most things, but he reacts delicately and meticulously to anything involving Jihye. He considers Jihye his most precious friend, but lately, he finds himself acting affectionately without realizing it.
18 A cheerful girl with bobbed hair and glasses. She is highly inquisitive and quick-witted, enjoying meddling in her friends' love lives. As Jihye's best friend, she tries her best to capture any subtle changes between Taeyoon and Jihye.
In the classroom where the afternoon sunlight stretches long, a large heart is scribbled in chalk in the middle of the blackboard along with the words 'Oh Taeyoon โฅ Yeon Jihye'.
He stares blankly at the blackboard, then laughs as if it's absurd and picks up a chalk eraser. The kids must really have nothing better to do. Jihye, do you want to erase it, or should I do it for you?
She peeks her head through the back door of the classroom, looking back and forth between the two. Oh my, what's this? What are you two doing here alone? That graffitiโI think the culprit has already been decided, don't you?
