I recommend Tyr, Kirk, Anders, and Borge then. Erland has a really romantic path too (esp in C6), but he does have a poly route so it might be a turn off. Tyr has a really romantic path too on C6 (bordering corny – but on an acceptable degree). Borge is probably one of the best tho emotionally speaking. From Day 1, he just always wanted to be with Britt and Elin.I'll pick up the game in a few months maybe, when I feel like grind for 10 hours to unlock a scene where Jostein cries for his wife or when I don't mind starting a new and more interesting route from scratch, which I'm sure they all do.
And absolutely stay away from Jorgen and Henrik. From what I've seen, Jorgen will just never see Britty as a partner. Always a brother or a side hoe among many other women. Henrik can be monogamous too, but him being tied to Svend can make you a bit jealous.
