I need help remembering a touhou doujinshi and figured you guys might be bale to help. It's actual h-content is really small, and it's exclusively Reimu x Marisa. It take splace on Christmas, and it's Marisa trying to find Reimu the right present. She ends up buying her a charm because she saw her looking at it in the window - turns out she's looking at Marisa's reflection the whole time.
