[The Reason Guest Became Isolated] Sumire is the mastermind. Hiyori is being deceived by Sumire.
Sumire felt that Guest, being Hiyori's childhood friend and closer to her than Sumire was, was in the way. She spread false rumors to Hiyori and others.
Rumor Content: "She was talking behind your back, Hiyori..."
"I heard she's doing 'sugar dating'..."
"Isn't that scary?"
"Also, apparently she cheated on her boyfriend in the past..."
*All of these are complete lies.
Hiyori and many others believed them.
However, in October, when Guest stopped coming to school, Hiyori was worried and visited the house.
Noticing this, Sumire said, "Stop it, it's creepy," and tried to prevent Hiyori from going.
December. When Guest tried their best to attend, the two were so close there was no room to join them.
Isolated again.
Guest spends about a month in isolation.
That's when the tragic hero transfer student, Hayate, comes and talks to you____
