Wait. Did he erase Rix's memories of him?
I don't think he'd erase his memories of "Nuah"...
Because he knows how much Rix cherishes that, and it would be underhanded to erase those memories but not memories of him. He's not the type to do that, I think.
So... if there's any memory-erasing about to happen, I think it would be regarding memories of him.
Then he won't show up anymore.
What will happen to the story then? Will it be other people who remind Rix of this "new Nuah" that he can't remember? And then... what next?

So far, it feels like all the stories are incomplete. I'd understand a little if they were oneshots, but this is in chapters and they tease us with a "to be continued", and yet just when things appear to be progressing,
The next story crops up. Maybe there's a reason, like the stories would intersect eventually so we need to learn the stories of everyone separately beforehand, but it still is making the reader of the series feel unfulfilled, to say the least.

I was surprised when I saw a different manga, but lookong closely I could guess why it was accidentally uploaded here:
This manga's title:
Tensei-saki de Suterareta Node, Mofumofu-tachi to Oryouri Shimasu ~ Okazari Ouhi wa My Pace ni Saikyou DesuÂ
English title:I was abandoned at Reincarnation, so I will cook with Fluffy Animals ~ The Abandoned Crown Princess is the strongest at her own pace ~
That manga's title:
Tensei-saki wa moumoku youjo deshita-zense no kioku to mahou wo tayori ni ikinobimasu
English title: Blind girl isekai
Both have "Tensei-saki" and "moumoku" may have been similar to "mofumofu".

In everyone's sights, this is a tragedy, but to them, it must be a "happily ever after".To think of it another way, it's an empty "happy ending". They're "happy", by their own definition and conclusion, but that pretty intricate vase is simply empty inside, with nothing but wilted rose petals and a small amount of stale water.
Even Makoto knows this, that's why he will always reaffirm Kei's feelings,
"Do you love me?"
yearning for something that he deems is wiithin his arms, but he won't ever fully have, and he will always recieve the same, almost automated answer:
"Yes".
This is their "happy story", the ending Makoto thought was the only one possible for him to achieve "happiness".
I was seriously thinking that Makoto would be the shy, honor student type who would typically relent at the face of temptation of his beloved person, but then push him away after feeling loneliness and sadness that his feelings aren't requited. Then, Kei would realize what a nice person Makoto had been. He realizes how mean he was to Makoto and how awful he had been to his girlfriend, three-timing(two timing? Including or excluding the other lady...) her like that, and breaking up with her. Maybe she'll turn out yandere and Makoto saves the day, and Kei decides to not date and focus on himself and his studies, to make up for his rotten deeds. Then, after sometime Makoto meets him once more, and they catch up together and end up with one another. Never mind cliche, I kind of just expected that. Maybe even wanted that.

At first I had thought this story would be the typical F4 and entire school vs. One girl who stands up to them, but even though it has a similar concept, it kind of feels relatively refreshing to me... maybe because there's no immediate falling in love for the heroine? Maybe because she was already bullied from the start? Maybe because of her past? Or maybe because one can sympathize more with her?
I'm super looking forward to the next part of the story!
That was... fast. He fell in love faster than she could say her name. It's like the way classic fairytale princes fell in love with their princesses/fair maidens, and I wouldn't wonder if she was transported into one.
It would be nice if he expanded more on why he fell in love with her, apart from the "you're beautiful", but I don't think that's possible. As it is, the main thing that pushes the story forward is the heroine's insecurity and her prince's love.
