Yes it is. Not a literal stranger, but practically one.
At this stage, they've only had one night stand and it's no base for a marriage. Which FC is mature enough to know.
I know he tries hard, but the girl doesn't have feelings for him (yet. They'll end up together i know) so atm he's just a guy (who has power over FC's job btw) courting a girl who doesn't even like him back. ╮( ̄▽ ̄)╭
I definitely do not think he needs to force her into marriage or she must accept him....but that's why he suggested getting to know each other at least(I'm glad he suggested that)....I'm just saying she should be careful the way she treats him....
And another thing is that he doesn't know her trauma...so he is just thinking of what the right thing to do is.

I hope she stops pushing away....because it will hurt him if she keeps treating him like a stranger.....its kinda disrespectful
