It’s actually a side story, the main story was concluded with the last season finale!

This is the raws if you wanna confirm lol I think it's similar to what you've said but I don't know korean
Haha I just saw the notice about that too. Oh well. I still think it'd fit as a flashback
For anyone who doesn't remember, Andrea's brother revealed to him that he was the "brother" Flynn had been looking for and that Andrea wouldn't remember because his brother had cut his horns off twice. (Which caused him to forget his rich family when his brother did it the first time and he ended up in the orphanage with Flynn).
So basically I'm getting this is a flashback to when they were growing up in the orphanage together from Andrea's POV and his feelings and thoughts then and how he disappeared from Flynn's life.
After this we'll prob flash forward to end of last season where they were in the snowstorm with the gunshot wound and all that.
