Spring in Seoul is really beautiful, the weather is cool and pleasant, the most prominent are the typical flowers such as cherry blossoms, apricot blossoms... the streets in Seoul are filled with peach blossoms, or the riverside paths under the blooming cherry trees... Kim Joon Goo is currently walking on the street, watching the cherry blossoms flying in the wind. Suddenly he is attracted by a flower shop on the side of the road, his pupils dilate when he sees the scene of a girl watering flowers, no... this is an angel, she is really beautiful, as beautiful as an angel.. Goo feels his heart skip a beat.
