Uwagakiai (ウワガキアイ) - Part 1/ BE 2 - English Translation (in CC)

Game is FREE on Steam, JPN language only - store.steampowered.com/app/23...
Hi all! This part doubles as BE 2/ the intro, as you can't really continue into the game until you get the passcode for the 4th door (which is 1217). This game is initially point and click, so you will not see my mouse clicks for now (your movements are heavily restricted in the beginning).
I will try to do my best on this translation. Again, I'm a non-native, so there may be errors. This is just for fun. Thanks!

I wanted to share an important note: The green text (I, you, he, etc) refers to the main character (MC). The purple-ish text (I, you, etc) refers to 'her'. We will find out more about 'her' later, but everything green refers to the main character specifically, the purple is 'her'! I will try my best to clarify in text, as it's hard to distinguish between the two if you're colorblind D: Please let me know if I missed anything!
