Love Live! Nijigasaki High School Idol Club (Season 2): Slumber Party

From Episode 10, where the Nijigasaki Idol Club were staying over Shizuku Osaka's house for a slumber party thanks to Kasumi and her plan to show off how she's the club's president once the group had their fun from shopping in different stores to a game created by Rina where the player who can find and collect the most amount of cats once time runs out wins (think Pokemon Go but with cats). During the game, Shioriko questioned Lanzhu about what was she wanted to do, she said that she wants to take a photo with the entire club, and Shioriko suggested taking one with her first. While taking the photo, they both realized that they have made progress in the game. After the game ended, Yu, the winner of the game, asks the rest of the Club to come up with lyrics for her song as her prize. That night, the Club writes lyrics for what eventually became "Love U My Friends".
