Love Begins in the World of If Episode 2

After peering into the shrine's mirror, Akihito wakes up to find his workplace completely transformed. His once cold colleagues now greet him with smiles, and his admired colleague, Ogami, is suddenly warm and kind. The lonely days he once knew seem like a distant memory as he becomes a valued and appreciated member of the team. However, the problems he expected to face have mysteriously disappeared, with all records and evidence wiped clean. Disturbed by this "unknown past" that everyone around him seems to share, Akihito returns to Lake Mirror Shrine, where he learns about the mirror's legend and begins to suspect he's in a parallel world where an "ideal version" of himself exists. As he grows closer to Ogami, Akihito starts imagining a future in this new world, a future where things could be different and better. (Source: Japanese = mbs.jp || Translation = MyDramaList)
