Does anyone know the name of this manga? I can't remember whether it's a oneshot or not, or an extra. But I remember that there was this boy (seme) who finds a spirit (actual small one) and catches in his hand and starts playing with it. And then something happens an they did it when the spirit becomes big, but cannot turn back to a spirit because they did it.
Thanks so much! I have been trying to find it but no luck
