Straight Outta Manhwa

Seon-Nyeo Han hears about an old romance manhwa from more than a decade ago, with a female lead character whose face and name are the same as hers. She obtains a copy of that manhwa by luck, and falls asleep while reading it. When she wakes up, she finds Nam-Wook Cheon, the male lead character, lying next to her. From the moment he comes "straight out of manhwa," Seon-Nyeo's normal school life begins to go awry!
