Kel is obsessing over keeping Sunny (and Mari. but Mari is dropped so it'll be FUN to navigate that level of stress) safe because big bro feelings and loads of guilt.
Basil is not someone I want to ship as long as he doesn't get time to process a few things so for now he's just in a 'no' territory. should he meet the right person MAYBE? but for now I'm more interested in finding him the right pokemon (I am also shamelessly into kelbasil so...)
Atem is married to his kingdom and his duties meaning he'd need to 'mature' a lot post 'romance is part of the job for a pharaoh' phase. Again, tho- married to Egypt and taking Board Games as lovers, basically.
My main ship in the YGO franchise is Judai and Johan from GX for some weird reason so I'm not even walking in with big preferences, he's just very focused on his work bfore anything else
the ONLY ONE with a romantic interest is Sunny (in ) and it's Complicated (TM) while in he's still an hikikomori but I see a prompt about magic and I'm toossing him there TOMORROW when I have time
In Lab Sunny is in love with Chuuta who is awful on so many levels considering the situation and I love it so much. He just figured it out, too, so there's that- and he refuses to fully acknowledge it or act on it so it's Very Weird.
