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.

After being fired, Lu Qingjiu finally decided to return to his hometown to farm.

At first, he started raising a pig, and then he found that the pig could solve more high-level math questions than he could.

After that, he started raising a flock of chickens, and then he found that his own fighting ability was one-tenth of that of a single chicken.

Finally, Lu Qingjiu finally realised that this old home wasn’t quite right… Especially a certain person by his side who constantly stared at him day in and day out.

Lu Qingjiu: “Are you drooling because of the spicy stir-fry I’m holding or because of me?”

Bai Yuehu pointed at the stir-fry.

Lu Qingjiu: “Then can you let go??”

Bai Yuehu reluctantly glanced at Lu Qingjiu’s arm, before loosening his teeth.
