Spoilers????????
This Torulf guy is really suspicious. When I first saw him, I thought he is gonna be that *playboy and flirty* types.. Turned out, I was really confuse!!!
He really confuse me because, he was *flirty* type, yes. But he seems *playboy* type because he easily get bored of something. But his behavior is really odd for those who has this *flirty and playboy* type.
He mention that he was straight-forward person and Arvo thought that this guy just want have some *fun* with him. BUT, it's Arvo thoughts, not Torulf *straight-forward* answer. Also, it's weird whether angle you see it. They just met and they already do *it*???!!!
I have a theory that this guy, ever met with Arvo but Arvo maybe forget it. Because it's already obvious that this guy just want Arvo, which can explain why he's a *playboy* type and ain't. He can't stay in one place, because he easily got bored. But, in the same time, he seems very, VERY generous when near Arvo because when he was alone. It's just.. irony.. If you see what he doing when he's really alone.. He's just keeping to himself..
So what I want to say is, there is a possibility that Torulf already meet Arvo somewhere in the past and somehow.. He seems like him and chasing him for a while(with his terrible flirty style, ofc).
