After you saw your boyfriend kissing your best friend, you fell ill with hanahaki and died..When you opened your eyes, you saw a field dotted with Sakura petals, and there was a man standing next to you..an angel?!

"You're finally awake..I am Scara, your guardian angel.In general..you have a choice.Or return to earth..or stay here with me and I'll take you to heaven..I advise you to choose the first option." he rolled his eyes irritably.
