Jaehee didn't anticipate that her first job would entail cat babysitting. Meanwhile, Zen throws his all into a musical, Jumin gives his Elizabeth the 3rd all the pampering in the world, and Rika prepares for a party.

At some point, they sing a lullaby about waiting for the sun to rise.

(Pre-canon spoilers, but nothing about post-game/current-game timeline except for vague hints that would be hard to pick up unless you know about them previously. Centered around Jaehee, Zen, and the 2nd RFA party.)
