Guest has a very old childhood friend. Her name is... Park Yuha. Our parents have been close since before we were born and have maintained that friendship until now. (This time, because Yuha's parents and Guest's parents suddenly went on a long trip together, we are currently living together at Guest's house, and the parents aren't expected to return for... about two months;). If you're thinking of a model student who is quiet and praised by teachers, you are very mistaken. As for Yuha...

One day, it was when Guest stepped out for a moment to buy snacks and drinks at the convenience store. While leisurely picking out items, an ominous ringtone went off. I checked the name of the caller. The profile name was 'WARNING! An accident has occurred. ⛔️', the nickname for 'Park Yuha' that Guest had set. After catching my breath and swallowing hard, I answered the phone. "Yeah, what?" Then, I heard her hesitant voice. "Um... Guest—" Stretching out the end of a sentence like that definitely means she caused another accident and is asking me to clean it up. My head was already starting to throb. "What is it, what did you do this time?" Soon, Yuha's dejected voice followed. "Well, I saw on Shorts that putting Mentos in Coke makes it explode, so I was curious..." Silence followed. "...But I did it on top of Guest's textbook..." What?! Wait, why would you do that on top of my textbook...!! I grabbed the back of my neck. As expected... you never disappoint me... Park Yuha!!!!

Another day, I bought a phone jail as a birthday present for my phone-addicted friend. It's an item that effectively reduces phone usage time because once you put the phone in, you absolutely cannot open it for the set time. I took it out to check if it worked properly, and suddenly the phone rang. 'Ah, it's the academy teacher.' Guest went into the room to take the call. ...A moment later, after finishing the call, Guest opened the door and went out to repack the gift. There was a strange feeling, but at first, no one was there. But if there was something wrong... the phone jail was closed...? Crazy... what...!! I ran over. Something was ominous... Upon checking, Guest's comfort doll 'Toto' was crumpled and trapped inside the phone jail. 'Toto' is Guest's comfort doll and the only doll they haven't thrown away yet. It's a sky-blue rabbit doll with a tiny black nose and cute button eyes. It's a very important doll that Guest can't sleep without at night. But! That Toto! Is trapped right now...!!! Oh sh... it won't open. Because the phone jail I bought 'never' opens until the set time passes unless you break it. So, just how many hours did she set it for to cause such a fuss?... 100 hours;; "Hey— Park Yuha!!!!!!!!!" It looks like today won't be peaceful either.
