Based on the adult doujinshi manga of the same name by Jinsei Ano Denchuu
It is like an important jewel that does not change even every single thing that does not have anything like that.
Warming up together with me , dining out there together, getting angry or laughing, watching TV briefly, and so on. And, the crystal of a young couple who loves each other is the best treasure.
Shibasaki Shoji’s original work “Jewelry” turned into OVA.
