I spend a lot of time with her, often petting and kissing her, but there's still no dialogue about sleep mode. Can you tell me if I'm doing everything correctly? What conditions are required to unlock the ability to sleep with Jun? (Sorry for my English, I'm from Russia and translated everything using Google Translate. By the way, hi from Russia)

多提升她的同理心，到达1000左右就可以了，这位来自俄罗斯的朋友，祝你玩的愉快
