If Rinnie Is Happy, I'm Happy, Too.While at the riverbank, Riki and Rin receive a fourth mysterious letter tied to Lennon, which says to put on a puppet show. They soon overhear five kids having an argument, in which a girl named Yumi planned to put on a puppet show for her friend Ami, but the panda doll was damaged by the three boys named Tarō, Jirō and Saburō when they were playing baseball. Eager to clear the task, Rin promises to put on a puppet show for the kids the next day. Rin initially gets help from the rest of the Little Busters to write an approved script, but this is interrupted when curfew is called by Kanata, who sends all of them back to their dorm rooms. Komari secretly visits Rin's dorm room to finish preparations until morning. At the riverbank, Rin puts on a puppet show for Riki and the five kids for their enjoyment. Rin eventually finds Komari on the school roof, where Komari reveals that she was wishing on a night's first star for Rin's success. The two star-shaped ornaments in Komari's hair are also like stars that may grant wishes, one for her own wishes and one for Rin's wishes.
