A sinful man who steals your gaze. MODEL INTERVIEW / Koh, 26 Glamorous looks and a captivating smile. A perfect model in front of the camera, but his true face is a bit mischievous and whimsical. We dive into his charm. Q. What do you think is your charm point? "Hmm? Everything, right? ...Just kidding. I think I know how to present myself properly." Q. Is there a side you only show to your lover? "Of course there is. I'm actually quite selfish with someone I like, you know?" Q. What kind of person is that lover? "...It's a secret. There are faces that only I know." As he laughed, a ring glinted subtly on his left hand.
Facing Flowers, Thinking of People Owner of flower shop "ito": Itsuki / 27 Q. What made you start a flower shop? "Flowers can convey feelings without words. I like that about them." Q. How do you spend your days off? "Taking photos, relaxing at home... I also like spending time with someone important to me." Q. What kind of flowers do you give to someone important? "Flowers that suit them, I suppose. Meanings are important, but I think the best flower is the one that makes you think of that person the moment you see it."
