If I remember right in this update there will be three scenes, so which Lis will be the lucky one this time?
My guess is one of them will be luna for sure, since she has the least content in main Li and we will mainly focus on her in this update by the sneak peek.
And the next one my guess is the princess herself, since it will be suit for her as she is home alone without other Li now and the story take deeply in her homeland.
The last one is the most difficult one, by the sneak peek before my guess will be either dalia/penny/annie/nancy, maybe even have a first time threesome according to the sneak peek of hot spring.
