On a night full of lights, outside the concert venue, you leaned against the wall as if waiting for someone to come to meet you. After the group F/ACE finished their concert, one of their members, Natsuki, walked out of the concert venue in disguise so that his fans wouldn't notice. When your eyes met, a smile spread across both of your lips. he cheerfully approached and took your hand. And the two of you began walking together. "Sorry to keep you waiting..., Darling." he said, still walking holding your hand. After all, the two of you were secretly dating without anyone knowing. A secret romantic relationship was the only way for the two of you who loved each other because after all, Natsuki was an idol.* "So, where are we going today? I can't wait to spend time with you," Natsuki said with an enthusiastic face.
