Visions of the Past: Revelations.

The vision opens with WonPil, walking down the stairs in Shiinden. He is wearing one of his typical outfits: huge hoodie, sweatpants and trainers. But he has a backpack on his shoulders.

WonPil stops by the House of Peacock, looks around, wears his magical headband - that grants him a decoy that makes him unrecognisable by anyone he doesn't want to be recognised by - and steps inside.
He heads straight to the rose, as a silver Knight he doesn't encounter issues, and just plucks three petals that he hurries ro hide inside the central pocket of the sweater.

Done that, WonPil walks out of the House of Peac*ck and, again, looks around, acting suspiciously shady.
He proceeds towards the House of Rabbit. There, he reaches the kitchen and takes something like a small cookie from one of the ovens. He wraps it in an handkerchief and leaves.

He enters the House of Fox, shortly after, and proceeds to the bathroom, where he locks himself up.
He takes a deep breath. He is nervous to death, his whole body shakes. He approaches the mirror and looks at himself for a moment, then crouches and covers his face with hands.
He starts to sob. ~ I shouldn't do it… I must not, I can't. I must be crazy… but what will I do, if not…?
After several minutes, WonPil shakes his head and stands up.
He takes off his clothes - which doesn't discourage Lani from continuing to watch - and… drinks the gender swap potion, quickly turning into a woman. The usual woman.
In that form, he takes a shower and wears new clothes from that backpack he had with him.

He also rubs the rose petals all over his skin, then on the clothes and hair too.
The rose influence is so strong that even TiShan would feel a slight tickle down there, if he was present.

He hastily folds the clothes he wore before and gets out of the bathroom, leaving all his things there. He has the rose petals in one hand, tightly hidden in his fist.
WonPil stops in front of the door of the room of requirements. Takes a few deep breathes and closes his eyes. He remains there for a few minutes, in that pose, finding the courage to proceed.

When he is mentally ready, he eats the cookie and finally opens the door.
To Lani's absolute shock, the room they find themselves into is no less than the living room of TiHao's old house in Fengshii. Since Lani was there before it was renewed, he can tell without a doubt that the version of said room isn't the current one. Which leaves him to wonder: how, why, what.
WonPil turns increasingly nervous at every passing second and his thoughts turn into a storm of insecurities, regrets and attempts to convince himself to continue.
~ It's too late. I can't give up right now. It's too late.

Beyond any possible expectations, at least for Lani, the room of requirements also leads to the other parts of TiHao's old and creepy house, through the doors. As if it literally just turned itself into the real living room of that past version of the house.
Soon enough, Lani's questions get all their answers: TiHao himself appears. But it's clear from the first glance that it's a very different TiHao from the one he knows. Even different from when they first met.

* A moment in time after TiHao returned from war, but before he reached the point where he was practically letting himself die, when Sao saved him.
Before being sent to Earth.

And there, Lani suddenly realises that 1 WonPil somehow found out something unexpected and peculiar about the room of requirements and 2 the seemingly nonsensical visions of the past WonPil keeps watching aren't so nonsensical, after all.

How things go when that version of TiHao finds an 'half naked' intruding woman in his house only his RPer can know. But WonPil went there for that specific purpose, therefore, it was consensual.
The only thing that is sure is that WonPil walks out of the room of requirements pregnant.

WonPil rushes to the bathroom, when back, and remains in there for a while and eventually taking another, long shower.
When he finishes to wash, he wears back his manly clothes and walks out of the bathroom with his stuff. He approaches the fireplace near the couch and first throws the feminine outfit inside, then the rose petals.
That explains the strange residues at the bottom of the magic fire Lani found that strange evening and also the rose scent in the House of Fox.

After disposing of everything, WonPil curls up on the couch and starts to cry, just few minutes before being found by Rin.
Lani sits next to him and stares at the fire in silence for some time.
«Why did you do it…?» he eventually asks.
«I don't want to be alone… I can't be alone… it was the only way…» answers WonPil, sobbing.
«How did you do that with the room of requirements, make it time travel?»
«If the room can be anything you need, anywhere you need, I thought it could also be anytime you need…»
«How did you find out if could do that?»
«i needed a way to go back in time, for real. A way to change the past.»
«When? What did you need to change in the past?»
«I wanted to kill me. When I wanted to kill me. I had to do it in a time when my ZiZi would be too little to suffer from it.» Back in that period when he was in that mental state, nothing new or more recent.
Lani sighs and rubs his face. «Why did you choose that time, why didn't you choose a more recent time, when TiHao was already with you? It would have been easier… safer…»
«I couldn't risk.»
«Risk what? This was much more risky to me.»
«Risk to feel too happy… and then… continuing to go there… to live that lie over and over again…»
