A teenager who unexpectedly gets transported to the modern world from ‘the world of the immortals’ . He finds himself in the body of an ordinary guy. He wants to go back to his world and for that, he will have to practice to get stronger and investigate the reason why and how he crossed through to this world.

On the first day Yuna became a class teacher, she became well-known in school because of her looks. On the second day of becoming a class teacher, a student secretly took photos of her with his phone and was called to the principal’s office with his Guardian. The person who showed up turned out to be Yuna’s university crush, Xiao Chen.

To Yuna’s surprise, Xiao Chen was the elder brother of the very student whose class she manages. She also realized that this rebellious student causes trouble two or three days out of every week, indirectly giving them many chances to meet.

…

When they reunite again, Yuna is puzzled. Wasn’t Xiao Chen a poor young master in the past? How come he’s now driving luxury cars and living in mansions?

Xiao Chen is also puzzled. Wasn’t Yuna a rich daddy’s girl in the past? How come she’s now dressing plainly and squeezing onto public transport??

…

In the eyes of her students, Yuna is very beautiful but has always been diligent and thrifty, with little interest in money.

However, one day a Rolls Royce showed up outside school, waiting. Upon seeing Yuna, the chauffeur respectfully opened the door for her, “Miss Yuna, please get in.”

From that day forth, her true identity set off huge discussions in school.
