“I have liked you for a while now,” starts Chul-soo, a ruddy-cheeked twelve-year-old boy who seems to be confessing to someone.
Chul-soo says that he waited for the other person in school all the time and even ate spicy rice cakes even when he can’t actually eat spicy food. He says he sees her face every night before he goes to sleep and thinks about her as soon as they wake up. “I like you,” he confesses drily. The girl happily answers that she likes him too.
How cute, except it turns out that they were only practicing reading lines in an acting training course. Their trainer sighs and asks Chul-soo how the experience was, and whether he was nervous. Chul-soo says he doesn’t really know. The teacher then asks everybody else if it seemed like they had a connection. The kids say it seemed like they didn’t like each other. The trainer agrees and lectures them that acting is supposed to make the audience believe that there is a connection even when there isn’t. He tells him that he doesn’t feel love or any emotion for that matter when Chul-soo looks at the girl, Young-hee.
The teacher then asks Chul-soo to look at how pretty Young-hee is. Chul-soo just looks away as the teacher drones on about how if it were him, his heart would be fluttering. The kids seem to agree. She is a pretty girl. The teacher then tells him an important lesson. In order to grow, there must be suffering. Chul-soo looks away and directs his attention to another classmate, Soo-hyun.
Later on, we see Chul-soo hear the teacher tell his mom that while Chul-soo is doing great, he seems to struggle to act with girls. Mom thinks it’s because he’s still young. Teacher agrees. Chul-soo scratches at a blooming mark on his neck.
Chul-soo’s eavesdropping gets halted when Young-hee calls him and urges him back to the training room. She hands him a box of chocolates and a letter, all pink and feminine, and Chul-soo accepts them apprehensively. Chul-soo scratches his neck again.
Young-hee asks Chul-soo if he doesn’t like her. But before Chul-soo could answer, Soo-hyun barges into the room and instantly teases them. Chul-soo vehemently denies it and promptly runs off from the training room. Soo-hyun follows him.
Outside, Soo-hyun is seen snacking on the chocolates that Young-hee gave to Chul-soo. Soo-hyun asks Chul-soo if Young-hee truly didn’t confess earlier. Chul-soo says not really, and he’s right, she hasn’t really confessed just yet.
Soo-hyun asks if he doesn’t like her when she’s so pretty, no, not just pretty, but the prettiest in their school. Soo-hyun then lectures him that maybe it’s because Chul-soo is still young but when a girl asks you out, you just say yes and try things out. Boy, you are also a kid! Soo-hyun proceeds to say they’re already twelve and when they’re much older, they’re going to have a harder time meeting people. Hilarious!
Soo-hyun then teases him that he’s so much more popular than expected and ruffles Chul-soo’s hair. It’s a moment that is terribly new to Chul-soo and he likes it. Soo-hyun then leans close to him and notices a greenish emboss on Chul-soo’s neck. It looks like a bug bite and Soo-hyun asks about it. Their moment gets interrupted when Soo-hyun gets called to go home, leaving a smiling Chul-soo scratching again at his mark.
