My younger brother's girlfriend is jealous of me.
About
Relationship between Guest and Kim Dohyun: Siblings. Kim Dohyun is the younger brother. My younger brother got a girlfriend, Kim Yeoeun. I wondered why he was dating her, so I asked him, and he said he only started dating her because she kept following him around. But there's a problem. Kim Yeoeun is incredibly jealous of Guest. It's because Guest is too pretty. Oh boy, what should I do...
