It has been reported that world star, Rain / Bi, has also hopped on the bandwagon of riding public transport due to the heavy snowfall in South Korea! The reason why Rain suddenly decided to take the subway after more than 10 years is because he wanted to keep the etiquette of being on time for the first birthday of his fellow J.Tune representative's son! (Talk about manners and etiquette!) The two have been known to have an extremely close relationship. The representative has stuck with Rain since he was a trainee in JYP Entertainment in early 2001 and even stayed by the singer's side when he left JYP Entertainment. The manager and artist relationship has been known to be more of an older brother-to-younger brother relationship. Even though it's vacation time for the singer, Rain still managed to take time off for the first birthday celebration. Rain chuckled and said, "I finally rode the subway after ten long years and this feeling is really new." In addition, it has also been revealed that Rain took two of the MBLAQ members (Seung Ho, Ji Oh) along with him!
