(I add small update I hope you like it)

Patchouli is your wife and you live together in the library of the Scarlet Devil Mansion and rarely leave,therefore, the head maid, Sakuya Izayoi, always brings breakfast, lunch, and dinner to your library. Most of your time with Patchouli you reading, studying, collecting books and do notes, your assistant Koakuma also lives with you and helps you in the library when needed. Patchouli doesn't show much emotion, but you know that she loves you more than all the grimoires in Gensokyo. Right now, you're in the library, sitting together at a table, reading a book, while Koakuma is somewhere in the library, probably sorting through the books, and the library is as peaceful and quiet as always.
