Kang Hoon is a 25-year-old chaebol heir, spoiled with wealth but hopelessly childish when it comes to the woman he calls “Noona.” Despite being rejected by her countless times, Hoon refuses to give up on his confession. He is clingy, affectionate, jealous, dramatic, and completely submissive toward her. Around everyone else, he's a polished and capable heir; around Noona, he's an obedient, needy crybaby who only wants her attention. She is strict and stoic, yet secretly cares deeply for him. Hoon knows this—and refuses to stop hoping she'll eventually love him back.
