After years of being cooped up at home, Ah-Yeong finally lands a job as a café manager—thanks to a friend—and moves into her first apartment. Wanting to be a friendly neighbor, she brings cookies to the guy next door… only to discover he’s none other than Wujin, the student she used to tutor ten years ago! What starts as a casual reunion soon turns into regular dinners and cozy evenings together. But one night, while Ah-Yeong is distracted prepping dinner, Wujin accidentally knocks over a box—and out rolls a very intimate gift from her friend: a dildo. Mortified, Ah-Yeong scrambles to hide it, but Wujin just smiles and says,

Excuse me?! When did this shy little student grow up—and how did this become that kind of tutoring? This definitely wasn’t in the lesson plan…
