His face is scary and she thought he was her stalker in the beginning.

She even starts to think his words are refreshing! In this world where everyone needs to keep their tongue in check, “Guardian Angel” expresses what one really thinks with plenty of sarcasm… This is how a hilarious and refreshing working life of Hikari and Guardian Angel starts!
