I was actually watching the first episode on a site when the subtitles began to act up so I decided to see if it had any official versions by kbs or sbc on Youtube. I found it on a different channel but the introduction scene (which is what I've watched so far) is different. The site only has the FL and the YT upload has both ML and FL's intro interspersed.

I thought it was weird and didn't want to lose out to bonus scenes or such. Is it the same with someone else?
