Looking for Arashi fans I met 2 years ago

Ah, I haven't posted here for loooong time....

Arashi boys went back to South Korea and played concerts this weekend in Seoul. Reading reports and articles about it reminds me of their first concert in Seoul.

I don't know how many Korean Arashi fans are here, but I'd like to get in touch with fans whom I met and talked with at the first Seoul concerts in 2006. Though I'm not sure if they are still fans of Arashi or not....

I forgot to exchange names and email adderesses with them and I always regret it. I've wanted to search for them, but didn't know what to do.... Probably, it'd be too late to post here but I hope any of them (or their friends) happened to read this post and contact me.

Here is the details of them:

In the afternoon of Sat. 11 November, I joined the queue for Arashi concert goods, and while I was on the queue I chatted with 4 girls from Daejeon (대전). Two of them were first-year university students and others were high school students -  one girl was 1st grade and another was 2nd grade (wearing glasses).

They told me that they came to Seoul from Daejeon with other Arashi fans for the Seoul concert by hired bus (or car). All of them attended 2nd concert on Sat., 11 November. The 2nd grade high school girl had a ticket of arena area, while the 1st grade high school girl had a ticket for stand L or C8 area. Both university students had tickets for stand L or C15 area.

We talked in Japanese most of the time, as I could speak only basic Korean.

As I didn't have a ticket for Saturday concerts, I said goodbye to them when the guard started to form a queue for audience of 2nd concert. After I had a snack beside the Olympic Hall, I met them on the queue again and chatted for a while. Then the queue started to move towards the entrance of the Hall, so we parted there. My memory is quite hazy, but I think I asked their names then. The 2nd grade high school girl's family name was Chi(?) or something like that, while the 1st grade high school girl's family name was Lee (이 or 리, I think).

Well, they might not remember me already, but I just wanna say hello again if they still love Arashi and remember the time we talked together. And if they got tickets for this weekend concerts, I hope that they enjoyed as much as I did at Arashi concerts for the past 2 years!
