(Liza's POV)

Before I start anything, I had to settle down in Donghae's cabin. It was small but thankfully Donghae's cabin had a spare room. After all, it's a campsite. Once I settled in, Donghae began his report on the grumpy campers.

Donghae: The camp officially started two days ago. Everything was going fine. Those three campers are originally happy and smiling when they first came here. They join in any games or activities with their new friends. Until the next day, I found out that they were grumpy and complaining that they hate camp all of a sudden when one counselor went to deliver their letters. Ever since yesterday, they were isolated from the other campers. It's weird, I know. 

Liza: I see. Do you see anything suspicious yesterday or the first day of camp?

Donghae: Well, if I remember correctly, I heard screams coming from the lake. I'm not sure if it's a happy scream or a call for help. I saw two figures walking and talking hanging around at the other end of the campsite. I'm not sure what are they. By the time I want to check it out, they disappeared. I suspect someone has kidnapped these three campers and make them feel unhappy. 

Liza: I thought so too. What about the campers? Did they do anything other than being grumpy?

Donghae: Yes. One was beating the pillow until it was ruined. Two of them were kicking their beds until one leg of the bed was broken. It was terrible. Just this morning, one kid became grumpy as well, hurting the other kids. Take a look at this video I've recorded of the recent grumpy kid.

Kid #1: Hey there. Where have you been all morning? Wanna go and swim in the lake?

Kid #2: Are you tricking on me?

Kid #1: Are you okay? You looked very grouchy since morning. Do you need any help?

Kid #2: (grabbing the shirt) Get off my case, you brat!!!

Kid #1: Hey!! What are you doing?!

(the kid lifted him up and throw him onto the ground, hurting him. The kid ran away and the kid who got hurt ran off, crying)

Donghae: Mr Woods, me and the other counselors were worried about them. That's where I need you to have to look for any mysterious clues and suspicious incidents around this camp. Find out who or what is making these kids all grumpy and hateful. 

Liza: You can count me in, Donghae. 

Donghae: Good. I'll be around to help you if you need any. Now, for your gadgets. Follow me to my garage.

Looking at that video makes me feel very shocked. I can't believe kids are becoming like this nowadays. And another thing. I don't think kids like him are that strong to the extend like a professional wrestler. This is very peculiar. I was still thinking about the video clip when we reached the garage. Woah! Donghae transformed his garage into a laboratory, only smaller.

Donghae: Welcome to my gadget inventing lair. I know it's not as big as R.A.M.'s laboratory. At least I have a place to do my creation. Anyways, here are your gadgets for the mission. Because I have a feeling you might be doing some traveling and getting stuff they need to feel comfortable or meeting up with the parents about their current condition, these gadgets will come in very handy. First is the language translator ipad, which allows you to translate any languages people speak to you. It'll also help you on responding back to the people you're speaking to in their language. You can test it out when you're exploring the camp. Not all kids here can speak English, as they are from different countries.

Liza: Thanks. This could be a helpful tool for me. 

Donghae: The next gadget is the currency changer 2000. Designed to provide any currency to pay for anything you need like hotels, food, clothes, etc. Just insert your credit card into the ma
