Dear Diary,

Hi again, it's still me (Trinity), from HOPE University. My friend (Y/n) just finished her work with the children today. The children we're teaching just moved up from 3rd Grade. We are all going to miss them. I wish that we could get back at each other again when the time comes.

Right now... after a few hours passed, we decided to go on a hike at Mt. Ebott. (Y/n) was strangely familiar with that mysterious mountain. She would go on walks and camping with her family before, yet... I wonder she stopped going on a hike here.

I've heard from Mr. Rockwood that his wife passed away after a few years. He was arranged in a forced marriage with Mrs. (L/n). She would be (Y/n)'s stepmother. No wonder, her last name was changed.

The last thing I would remember was that Mrs. (L/n)... wasn't a really nice person. Ms. (Y/n) would often vent about her, well... she would throw those vents at me. I honestly wouldn't mind, but... for some reason, it just pained me so much to see her suffer from her stepmother's petty arguments. Mr. Rockwood wasn't even there for her the whole time, as he was really busy for work and almost had no time for the both of them to bond like those times.

Anyways, we had our friends Mr. Cole, Ms. Yamato, Ms. Williams, and Mr. Rickert. We settled in a tent and would sit around a bonfire like little kids. That was the greatest moment at that time...

Well, despite all that... I do hope my friend would still get on with what's happening in their household.

I closed my diary and went out of the tent. I looked around, nobody was up. Everyone was still asleep... as usual. I breathed a sigh and put a hood over my head and walk by the base of the mountain.

I sat by a rock, feeling the cool, gentle breeze. The nature's call... it was relaxing.

A thought came to my mind, wondering... Where did (Y/n) go?

...

"(Y/n)...?" I called out, but there was no response...

"(Y/n), where are you?" I called out again, but not a response was spoken back.

"Strange... did she go too far...?" I asked, and now I remember...

The talk we had... The monsters... Did she fall down a hole??

"Shoot... (Y/n), I'm coming!" I shouted, running to the mountain. Why didn't I think about this sooner?! She must've been hurt!

"(Y/n), I-" My eyes were widened at the sight. The hole was... indeed... deep. You can barely see the bottom... but, a faint tinge of yellow glowed down there...

"...(Y/n)?" I mumbled, but no response...

I heard footsteps and ran to hide behind a large rock. A guy, with such pale blonde hair, his tired eyes of blue and golden yellow... he walked into the cave. He rolled up his sleeves from his black turtleneck. Peering down, I could hear him laughing...
