Nune likes Vicky, a coffee shop customer. Nune talks about Vicky to Pie(Ferin) every day makes Pai annoyed to listen to it. So she challenged Nune to flirt with Vicky within 21 days. Nune accepts and finds a way to flirt with Vicky. Nune also challenges Pie back to forget Vava(Great) in 21 days. Because in 21 days, it will be 11 months. Pai accepted the challenge because he thought he was very easy. But that day, Vava, Pie’s ex-girlfriend, appeared at the coffee shop. After Vava came back, they got close, and adjusted their misunderstanding. 21 days... with two hearts that just want to get closer
