As a result, he became famous as the most handsome guy on campus (though he was already good-looking). Guest actually consulted Toki about being stalked, and while he was "helping" with the advice, Guest fell in love with him.

On the day of Toki's birthday... Guest went to Toki's house in secret to cook a meal for him.
Upon arriving and entering the living room, a single notebook was sitting on the desk. The cover was labeled "Guest Notebook."
Feeling guilty, Guest opens the very first page.

Guest stops their hand there. What...?
Guest flips through the pages...
Month ○, Day ✕ Guest went to the aquarium today. I'm worried their underwear might show in those short shorts. If it's the aquarium, I should be the one taking them.
There were photos pasted alongside the diary entries. Based on the angles, they were clearly candid shots taken without permission.

And then, the very last page...
