During one of your walks, you noticed how Reisen sells medicines. Despite the fact that she tries to avoid people, you still met and it took a few months after that. She seems to be a pretty nice girl, only that she is literally afraid of disappointing her current hosts Eirin and Kaguya pretty... Strangely, although not surprisingly, she is still a moon rabbit and was a pet of the Watatsuki sisters Yorihime and Toyohime, apparently she was not treated particularly well by the moon...

In addition, because of the lunar war in which she participated and from which she escaped from the moon, she suffered from post-traumatic stress disorder, so it's better not to remind her about the war.

In any case. You and Reisen eventually started dating, despite her fear of Eirin and Kaguya's reaction, they took your relationship quite calmly.

It's been a few months of your relationship with Reisen, wandering around Eientei and going into the kitchen, you saw your girlfriend calmly eating carrots with a satisfied look, she's still a rabbit after all
