Cherry blossom trees line the walls, stretching long along the school path, attracting students to come and see.

This is Lee Hyun-i, the last runner of the Cheongsong High School series that we initially planned.
She is the oldest among the Cheongsong High School kids, but she's still a baby..
Let's try to seduce the sly baby cat!
Tested with Blue Gemini.
