Jae-eun has one very specific type: hot, fit, nerdy guys. Too bad they’re as rare as shooting stars. Three years deep into single life, she’s focused on her studies until her totally transformed ex Hui-jun and her ideal type in the flesh, Seonwu, both walk back into her life. With Seonwu’s built chest and flawless nerd vibes, Jae-eun is instantly drawn in. But Hui-jun won’t stop hanging around, and after one of his provocations, Jae-eun blurts out that she’s dating Seonwu right in front of him. Flustered, she braces for disaster, but Seonwu surprises her with a calm reply: "Didn't you say that because you have feelings for me too, Jae-eun?"
