Shingo's Love: The Grieving Doll
Shingo no junjo! Kanashimi no Furansu ningyo
"Shingo's friend Mika gives him a doll that she won in a doll-making contest. But Shingo unintentionally breaks the doll and hurts Mika's feelings after being teased by boys at his school. Taking his sister Usagi's advice, Shingo decides to apologize, only to learn that Mika does not wish to see anyone." (source)
