So ML is a phycological patient.. He had an accident and had an unusual brain problem.. His brain created several subpersonalities who doesn't have the awareness of the existence of the main personality and they created their own illusionary individual world and lived in the brain of the main personality. This causes the main personality to have several brain damage and so he found phycologists to cure himself.. As his problem was very critical so many phycologists rejected him.. So he found the best phycologists in the US to cure him AKA our Fl...

No, She is not.. She is not the best phycologists but his assistant.. The doctor didn't want to take this job.. And our miserable/orphan/debt-ridden FL went to cure ML with a false identification.. As she is not a certified doctor, she faced problems when curing him.. She would hypnotize themselves and go to the illusionary world and help the sub-personalities to fulfill their wish or eliminate their resentment in order to cure them. After their resentment is eliminated the illusionary world will disappear and sub-personalities will merge with the main personality, coz they are basically a part of the main personality. And in every world FL and ML will fall for each other. But it is taboo to attach to the patient emotionally when curing them.. And also the main personality will forget about their experience when the sub-personality disappeared. So our FL was sad and wanted to run away after curing ML.
But there is a 1% chance that the main personality would not forget their experience and as the protagonist, ML didn't forget anything and pursuit the FL in the real world.. And in the end, they will happily live after...

It's the overall story.. Wanna know about individual world stories.. Then proceed

World 1: disable young master x rehabilitation doctor
ML was disabled after an accident caused by his stepbrother (who is Yue Lingying). FL became a rehabilitation doctor and helped ML eliminate his resentment against his dad and stepbrother. But the world didn't disappear because ML found out FL was lying to him and he imprisoned FL.. After some twists and turns ML was finally satisfied and the world disappeared.

World 2: prisoner x crossdresser prison guard
The smallest world. ML become a prisoner after taking his father's blame.. But when he found out he was deceived by his father he escape prison and punish his father and his new family. After he has no ambition for life so he returned to prison and started living there. FL entered the world as a prison guard. She cross-dressed as a male. ML found her interesting and fall in love. There was a doctor named Zhou Ying (previous Yue Linying) who was FL's friend and made ML jealous.. The story is basically about FL and ML's love.. The story ends with ML proving his innocence and getting out of prison.

World 3: young s*ave x s*ave owner
It is an ancient world. ML was born from a prostitute and was sold and FL was the richest person in the city who bought him. FL bought another person before who was Zhou Ying. FL sent Zhou Ying out of the mansion, as a result, his brother who is a general stanched everything from FL and FL become poor in just a night. FL and ML then went to another village and started living as siblings. A problem happened in the middle and FL was cast out of the world by mistake. When she returned already 15 years passed. The story ends with FL confessing her love surrounded by blazing flames.

World 4: twin young masters x fiancé
FL enter the world as a fiancé of the ML. As she entered she found she was going to the wedding hall and was attacked by some people. When she tried to run away she found out, the people attacked were actually The ML. She thought some mistake happened and she entered as any NCP's fiancé.. So she went away with the ML. But there was actually 2 sub personality in this world. ML was a twin and the older twin was sickly but pampered, and the younger twin was healthy but neglected. Two brothers hated each other and snatched each other things. When FL found out she was shocked. The story ends with two twins merged in one body (yes in an illusionary world everything can happen) and marrying FL. Oh there is also Zhou Ying as a villain there.

Now when FL returned to the real world after this she found several sub-personalities died because of unknown causes and damaging ML's brain. Only one sub-personality remain and she quickly went there to save him.

World 5: city lord x his bride
It is an ancient world. ML is a cute and silly city lord who wholeheartedly loved the city and his people. ML also wanted to be a monk in this world but was held back by his people. There was a rumor that he can't marry unless Buddha gave him a wife. And when FL appeared on the Buddha's platform, ML told that she was the bride given by Buddha to him and marry FL. Zhou Ying was killed on the wedding night of the protagonists with a gun which shouldn't be appeared in this world so FL knew there was a mysterious person in this world and tried to find him. Which led her to the ML. Silly White sheep ML turned out to be a big black wolf. He is the one who killed every other sub-personality. With Many twists and turns story ends with ML and FL growing old together in this world as it was ML's final wish.

World 6: (real world) powerful president x fake doctor and lord governor x FL (wait I am explaining)
After curing ML.. FL wanted to go back to the US. But ML who was already in love with FL tried various means to keep FL from going. And in this world we came to know that Zhou Ying is actually ML's silly friend and a sweetheart. After many conspiracy ML finally be with the FL. It is really funny how every deed of ML got exposed but FL couldn't scold him as she also lied in the first place about her identity and everything. They lived happily..

Not ever after because there is a but..

Remember the previous subpersonality killing other sub-personalities. There was a lord governor among them who was unwilling to die and actually take over ML's body in the real world after 5 years. It was funny how the lord governor of ancient time stumble living in the modern world. Like he wore the pant but didn't zip up and wore the coat but without the shirt under. He actually tried to cut his __ because he that was reacting to FL 🤣🤣🤣.. Well, our ML finally recovers by merging with the sub-personality, and with that the story ends.
