College student Miyako Hoshino is rather reserved around others. She usually spends her days in her bedroom crafting cosplay costumes. When her fifth‑grade sister Hinata brings her classmate Hana Shirosaki to their home, Miyako is immediately charmed by Hana"s adorable appearance.
Miyako attempts a variety of gestures, from encouraging Hana to wear cosplay outfits to offering her sweets. Initially this leaves Hana with a poor impression of Miyako, yet she remains determined to get closer to the angel who has appeared before her.
