After a passionate night with Kagura, Rein returned to their previously booked room with her. There they found three grinning ladies who immediately assaulted Kagura and started to ask her about all the juicy details.
Kagura was feeling a bit shy when the girls were asking her that type of questions but still she answered all of their questions obediently. Kagura was actually very grateful to them as she knew without them supporting her, it would have been extremely hard for her to understand the feeling of love. They also supported her last night by giving Rein to her for the whole night, even though they must have desired to spend time with Rein.
So for all these reasons, Kagura was grateful to all of them and she was willing to endure her shyness to fulfill their wish of listening to her love story.
