Krizza Steins was supposed to enjoy the concert of her favorite band, DAY6, but she was asked to direct the whole event instead! She thought it was really unfortunate, but she could not believe her luck when she personally met the members of the band, especially her ultimate bias, Young K a.k.a. Brian Kang. Then two weeks after, she moved to South Korea for a one-year work contract with one of the prestigious film company in the country. And the odds must have really been in her favor when Young K asked her to meet. What she thought was a simple fan-artist interaction between her and Young K actually grew into a close friendship. Can she hope for something more than a fan-service or friendship? Or should she remain a simple fan, who if had not been favored by luck that night, would have probably been non-existent for her bias?
