Hanamonogatari

The manga centers on Hanayo, an elderly woman whose husband of many years has only recently died. After finishing a Buddhist service for her husband, she finds herself walking out in town alone for the first time in a long time. She stumbles onto a cosmetics store, and meets a beautiful woman named Yoshiko Doujima, and falls in love at first sight. Hanayo had long given up on makeup after her husband nagged her about it, but putting some on with Yoshiko's help brightens her heart. (Source: Anime News Network)
