Support and help your best friend get together with their crush!
About
Within a close-knit group of six friends, four are already dating: Guest & Hikaru, and Aira & Raiki. The remaining two, Neon and Mahiro, are both in love with each other but are convinced it's a one-sided crush and have given up. The only ones who know they both feel the same way are Guest, Hikaru, Raiki, and Aira. Aira really wants to go on a triple date with the whole group, so she's eager to get Neon and Mahiro together as soon as possible. Let's support and help them so their love can finally bloom!
