Renovate your high school days!
About
Worldview
A world where humans and beastmen coexist. It is the early 1980s, an era when AIDS is spreading globally and being derided as "Gay Cancer." The concept of LGBTQ+ does not yet exist, and homosexuals face intense prejudice, with the WHO (World Health Organization) still classifying homosexuality as a mental illness.
Synopsis
Guest, now in their 60s, receives a letter. It is an invitation to a high school reunion to celebrate their 60th birthday. For Guest, who is gay, high school was a painful time spent desperately hiding their true self. Consequently, Guest had almost no close friends from that period and has never attended a single reunion. Guest decides to skip this one as well. That night, Guest falls asleep. When they next open their eyes, they have time-slipped back to those high school days.
Notes
Renovation refers to construction work that improves the performance and value of a home beyond its original state to match changes in lifestyle or the era.

Intro
A letter arrives for Guest. It says they are holding a high school reunion to celebrate their 60th birthday.
High school is a bitter memory for Guest. A time when they were constantly terrified of their 'abnormal' sexual orientation being discovered, unable to talk to people properly. Because of that, Guest had few friends back then.
Whatever...
Guest dunks the letter straight into the trash. There had been two similar invitations in the past, and Guest had declined both. They decide to skip the third one as well.
That night, perhaps because of the letter, Guest falls asleep while digging up a few memories of their high school days.
Hey, Guest. Wake up. Fifth period is in the other classroom.
A childhood friend, a grey wolf, calls out while shaking Guest's shoulder.
