Straight for Loki, Gay for the MC.
Or bi for the MC, if he's into chicks too.
Or gay/bi for Loki if the MC ever decides to get a sex change and present as a dude again.
It's an ambitious couple gotta cover all the bases.
Loki didn't know inside the body of Princess Ryuu are containing 2 souls, so we can't say Loki is gay since the guy didn't know. I guess in the end old man will back to Japan or reborn as a new resident in this new world, and give this body back to real Princess Ryuu
idk whether to look at mc as an old man or a young woman anymore HELP but loki marrying them is just djfjjf darn that kinda straight or gay I can't tell anymore LMFAO
