Seulgi might be a big nerd who dreams to have her own zoo and starts out her adult life as a vet, but she's also the smartest girl in school and the daughter of a chain hotel owner. 

Being rich was not so special in South Korea's most expensive private high school. Everyone was born rich. 

However, there was only one Park Chanyeol. The player who breaks girls' hearts and fights neighboring school scoundrels as his pastime. 

But when Seulgi's best friend Yeri declared that she's dating Chanyeol, Seulgi thinks she has to interfere. 

She just has to save her friend, especially because rumour has it that Chanyeol's kind of first date was at a hotel suite. Little did Seulgi know, she's going directly to the devil's trap.
