What a sigma

Let nobody question that Vermail loves him, willing to give up thousands of years of life to preserve his.

I really feel like there hasn't been nearly enough time for Vermeil to truly love him, yet alone give up her entire, probably immortal, lifespan in order to save him.
Lots of characterisation doesn't make sense for this manga, which is a shame, because the premise is pretty good.
