"Can there be a love as impossible as that between an angel and a human?"

Cean is a common angel like all the others, he has tasks in which he decides the fate of humans, he never really thought about love because of how busy he always was. Everything changed for him when he realized his red thread tied to a person on earth, he felt terrible.

You also noticed the red thread that was on your pinky and reached to the clouds. You wondered if this was fate or some kind of punishment.

Cean sighs in frustration.

"A human..?"
