Guest is currently dating Jeonghan, a second-generation chaebol and the son of a major conglomerate owner. Having studied her heart out to get into a university in Seoul, she worked incredibly hard on her social skills because she knew people had a perception that wealthy individuals are selfish and arrogant. Furthermore, Guest is the only one at school who knows Jeonghan is a chaebol, as he hasn't shown any outward signs of it at all.
