For a while, the Friday morning was relatively normal for Yui and she decided to stay in class during break and help out with the odd jobs in her mission to be 'Keima the model student'. It was soon to become awkward and embarrassing and the problem never occurred to her until the tidal wave hit. It arrived in the form of a PE lesson and as normal on Fridays, it was with class 2-D and it was boys in one classroom and girls in the other.

Don't look, don't look, don't look...

Changing herself without a classroom of boys around her was already hard enough, she didn't want to risk doing something completely and absolutely wrong so she resorted to covering his face with his PE clothes and waiting until everyone had gone away.

"What the hell are you doing, Otamega?" one of the boys asked in a slightly mocking tone, "Aren't you usually supposed to be playing on your PFP at this time?"

Yui was so intent on ignoring her surroundings that she didn't hear him and since he was ignored he wasn't bothered to pursue any further. It was customary to ignore him anyway. Soon, the classroom was empty and Yui was finally left alone to change. Not that she was looking forward to it at all and in the end, she was late for the lesson which made the PE teacher make her run laps around the circuit before she could participate. It practically almost killed Yui.

"Still rubbish in PE aren't you?" one of the boys noted mockingly when Yui fell down again.

"You're... so... lucky." Yui panted, "You get to play football with breaks in the middle."

The boy looked surprised, he ran to his friends and started chatted excitedly about something. For now, Yui wasn't interested. She'd only been able to run three laps in fifteen minutes and she was sure that walking was actually faster than running when it came to Keima, not that the teacher allowed it.

…

"The PE teacher was so mean. Why did he have to make me run like that?" Yui complained to Elsie, she suddenly thought of something, "Elsie, did Keima say anything about yesterday? My class has PE on that day."

Elsie laughed nervously at the implications of what Yui said and after some thought she said: "Man, I bet he was too focussed on the game to notice anyway."

"Game?" Yui asked, perplexed at what Elsie said.

"It's nothing. Seriously, I'm pretty sure he's not that sort of person." Elsie gibbered.

"Right, since it's lunch now, I will confront him about it."

God, I hope he's not a pervert.

…

Fuse Aoba looked into classroom 2-A and found the girl.

So she's Goido Yui, the daughter of a rich traditional family.

It was slightly annoying to see that she also seemed to be an avid gamer though it perplexed her as the research she'd done seemed to tell her that this wasn't supposed to be how she behaved. Nonetheless, she'd decided to confront her first and as she summoned up the courage, someone barged past behind her.

Ow... isn't that Keima?

…

"Keim- Yui-san, I want to talk to you for a moment." Yui said as she burst into the classroom. This earned her a few glares from around the classroom.

As she drew near Keima who was saving his game, Mio suddenly got in her way.

"Commoner, how dare you speak her name so casually." she said haughtily, crossing her arms.

"Mio, it been a while, hasn't it?" Yui burst out then realised her mistake.

"How dare you act so familiar..." she trailed off, "I don't even know why I'm talking with you!"

Keima finally butted in: "Mio, it's fine. Let him talk."

"Yui, it's because you're too nice that parasites keep coming to you, you need to know how to say no!" Mio complained, concerned for the wellbeing of her friend.

She doesn't seem to remember at all yet... to refer to me as a parasite...

"What did you want to talk about?" Keima smiled pleasantly at Yui.

"I-it's about PE yesterday." his cheeks coloured up.

At this point, Keima had spotted Aoba peeking in around the corner.

"Nothing much happened, don't worry. It was easier to move in fact." Keima replied bluffly.

Mio was confused as what they were saying: "Who is this man, what's this thing about PE lessons?"

She glanced at 'Keima' and Keima could see that she seemed to be battling something inside her.

"Nothing, just being erm... random." she finished lamely and as she knew that there was no way to converse properly with Keima with someone else around.

"I'll accompany you back to your classroom since I want to see Elsie as well." Keima said to Yui as he got up.

"A-are you sure you should accompany this vulgar man?" Mio asked, "there's a limit to how polite you should be."

I'll need to check up on her after this but for now...

"I'll be fine. Let's go Katsuragi-san." Keima said.

"Katsuragi..." Mio whispered, "Yui, is this man the reason you're so weird these days?"

Crap...

"Umm, Katsuragi, you should go on without me, I'll join you shortly." Keima said quickly, hoping he could get Yui away.

"Stop! Yui, if I remember correctly, he's that Otamegane who plays his games in class and you've been doing that recently. What's happening? You can tell me if that parasite has done something to you!" she said loudly.

I don't want to do physical things any time in anybody.

"Yui, Fuse's out there. Remember the lines." he whispered in his ear and then pushed her out of the classroom.

Mio seemed to run out of steam as 'Keima' left the classroom.

"That person really annoys me for some reason." Mio remarked.

"Why?"

"I don't know. For some reason, he reminds me of something distant... the flower banquet? No, that can't be right, I was dancing with..." Mio struggled to collect her thoughts.

"What do you remember?" Keima said, maybe too forcefully.

"Huh. What? Why would you want to know." Mio looked at her suspiciously.

"I don't know, I didn't see you that day so I thought you never attended." he picked his words carefully analysing what he could and couldn't say from the knowledge he had.

"I think I was dancing with Morita then but for the past few days I've been slightly uncertain about that. Last night, the feeling sort of went away and... I really don't know." she said helplessly, "In any case, it was a strange night because it felt like everything had changed. It couldn't be that simple."

So does that mean her memories have already been remodified. Wait... that also means that not everyone's going to be pestering me for a month!

"Yui, are you okay? It must that horrendous man, let's go confront him!" Mio said enthusiastically, steering them away from her subject.

"No thanks, I can cope on my own. Trust me." Keima said.

"If you say so then I'll see you later." she skipped away, presumably to buy an omelet-soba bread for lunch.

He quickly stepped outside the other door Yui had went out by to find Yui struggling with Aoba who now seemed to be rather distraught.

What the heck has been happening?
