While trying to come up with lyrics for a song, Kayo asks for help from Tamaki, who assumes she is writing a love poem and starts getting wild ideas. Later, Tamaki recalls how she first became friends with Yumine during elementary school. Wanting to play with Yumine, who didn't have any friends due to her poor health, Tamaki started designing her own board games that they could play together. As a result, Yumine came to smile more and soon became close friends with Tamaki. Back in the present, Tamaki is approached by a strange girl.
