He will prioritise Birgit over Britt, still he views MC as 2nd romantic interest, there is a lot of brotherly love intertwined with lust and romance, if you want a commited or more romantic route, I'd recommend Kirk, Tyr (personal favorite, but the hardest to romance), Ralf (Monogamous route), Borge, Anders (difficult to romance, but can be swayed with the right choices), Erland (one the coolest routes).
