Once upon a time, YulTi had it all. Until the management wants them to stop all interactions because Sones, or "Soulkeepers", as they like to call those who ship YulTi, are coming with crazy theories such as YulTi are in love, YulTi are not afraid to show their love for each other in public, Yuri is the man in the relationship because she's a top, that's why Tiffany is calling her Yuri Oppa. SM management team decided they need to stop this, so they came up with new ships being TaeNy and YoonYul.

But what if one day Yuri and Tiffany are left alone at their dorm? What will they do?
