Aleysha even challenged Rose to have sex with 3 people if she could stand it too. Him, Rose, and Richard. You know? Aleysha didn't really think that Rose would accept the request.
The first time, the crazy sex was awkward. Twice, they started to enjoy. Three times and so on… They had all lost their minds and dragged Sheila too to join in if the little girl caught her with an innocent face.
Rose was sad when she entered this strange world with Ricard, Aleysha, and Sheila. But even though her heart was cut to see Sheila being played by the two of them, the little girl seemed to enjoy it too with her tiny, red face.
In the end, Rose felt that all was well.
It's just that, unexpectedly, Haru asked to meet on Sheila's birthday, which time (she doesn't want to think about it anymore). Because Rose thought it would never happen. But when Rose heard Haru's confession, it all made sense.
