Xue Xi is forced to fall in love at first sight with this dangerous man on their first meeting. With death being the only other option, she makes the first move:

Han Dong works as an extra as well as a fortuneteller who foretells marriage fortunes extremely accurately. One day, he accidentally foretells his own fortune and discovers that he and a Mr. Golden will become “a match predestined by fate”.

Yuna, a 15 years old girl started playing the world’s first VRMMO. She has earned billions of yen in stocks. She confines herself in her house playing the game without going to school. Today, a huge update has arrived. She obtains a non-transferable rare bear outfit. But the equipment is so embarrassing that she can’t wear it even in the game. Furthermore, when she answers the survey regarding the new update and relaunches the game, she appears in unknown forest in a bear outfit. Where is this? Email from God? Different world? If she wears the bear outfit she’s a cheat, if she takes it off she’s a normal girl. Her adventure starts just like that. Yuna began doing as she liked.
