Hey... I guess, well, I'm probably dead by the time you're reading this and assuming why you're reading this is either Seto and Kano:
A. They told you
B. They told you and Haruka (a.k.a. you idiots messed up)
Or C. You found the note yourself
I'm also going to assume that this is Hibiya. So lots of crazy things have probably happened up until this point. Really, I think this is a no-brain-er. I'm just going to take guesses here:
Ayano is probably confused and trying to solve what the f is going on, Kido probably has trauma, Seto is probably holding back his feelings that way he can help everyone else can help, Kano probably barely deceives anyone anymore, Mary is probably trying to cheer Momo up, Momo is probably lonely, Takane... is probably Takane still, Hiyori... same goes for her and giving you a hard time still, and Haruka... well it really depends on if you guys told him or not.
Well, if you guys did tell Haruka... crap, I don't know, don't tell him anymore? Wait until August 15th? To put it simply, if you did and he's acting weird, then you guys f-ed up.
Just, when it's August 15th I'll tell you this, it'll probably return to that day, not August 14th since I'm messing with the whole unbeatable-heat-system-thing.
Yeah, this is a whole plan thing and blah, blah, blah.
Now, when it's two years later on August 15th I need you to make sure Hiyori doesn't "die" and you do it instead, not like you've done it before. Then again, you don't remember when you died when time repeats again. But seriously, make sure to do this and "no" is not an option since you know that one of you two are fated to "die" on that fateful day.
The plan should go out smoothly, but again, if you did tell him, you f-ed up, I cannot emphasize that anymore.
If you mess up and time repeats and if Seto and Kano do get their hands on the note and/or get told by Ayano and Kido make an excuse and drag Haruka out before anymore information is spilled.
Then again, the first time would mean he already knows about it and if you repeat... ugh, just make sure no more information reaches him.
I would tell the others about my plan, but let's face it, the dan is just full of (should I even put it nicely?) idiots. For 1, Ayano is not the smartest person I know, maybe smarter than Momo, but seriously, I know that she somehow got .05% on one of her homework assignment. 2, same goes for Momo. 3, Seto is a worrywart and if I were to tell him then he would probably panic whenever he's talking with Haruka. 4, Takane would probably not trust me and blabber her mouth off to Haruka on how much of a jerk I am. 5, Haruka probably still has him and that would just mess up my entire plan.
And now, here I am, telling a freaking 10-12 year old who was leaded by a rabbit and somehow smarter than the other teenagers here in a freaking text. (I know I'm over-exaggerating but this group has some bright moments and other times it's just face-palms from disbelief on how we came together).
I swear, this is definitely not how I planned this out to be.
Anyways, getting back to my plans, when you're finished reading this extremely long text and going outside, do NOT tell a single soul about this.
If the guys ask about what you found just say you found nothing.
If they constantly ask say something about the computer only having the password soda (don't judge) and nothing saved there and nothing in the recycle bin and tell them that there's probably no code to the note.
Only Ayano (her siblings too as long as they don't tell anyone else), and of course you, are allowed to know about the note.
