@angelight313_168 Thanks for the welcome 
I didn’t realise there was more than one Tunnel ! Actually that’s not strictly true. I watched the Time Travel one with Choi Jin-Hyuk (who after watching Rugal as well has become my favourite actor) and then did also watch what I believe was a Thai (?) version.
I’m just completely obsessed with all things Korean now 
My orginal bucket list for places to visit was:
1: Tokyo
2: Los Angeles
3: New York.
But now my list is:
1: South Korea
2: South Korea
3: South Korea …haha
I just wish I was a good learner/student because I’d dearly love to learn Korean so that I could watch them without subtitles
