(He definitely has it in him to be the scary father figure to anyone/everyone who wants to date his daughter. Sadly she had perished far too soon for that to be a worry. So maybe he is projecting some of his frustration on Yukari. But they both know he has a soft heart.)

I would have sacrificed myself for him without you asking. (Not that it would have made Curufin happy, but at least he would have been alive.)

Something is missing. You were willing to save him at any expense - that is an idea he should understand well. So how were you hurting him?
