I honestly think it is Minchan. Maybe my brain is playing tricks, but it looks like his colour palette in greyscale, not Seoho's.
yesss !! also from what we see of seoho he’s always so serious. so to me the expression shown in the eyes and brows gives more minchan.
True true^^ I was also looking at his hair. No bandana and his hair looks way too short in the back for it to be Seoho.
Also.. it's story about Bihwan and Minchan, so I fully expect them to go with Minchan being his hubby and endgame! If not, I'll riot (╯°Д °)╯╧╧ Jokes aside, it's likely Bihwan needed to become attached to Seoho for him to find his family and partner. I doubt he'd go anywhere near Minchan if not for what happened in the past
did anyone else notice that bihwan’s lover more so resembled minchan? i don’t know how to explain it. maybe it was just the expression, but like i saw the black and white pic and was like oh that’s so minchan.
