(Spoilers?) What’s your thoughts about Fuyutsuki being in-love with Yui?

I’m a absolute nerd for this old man (and his n1 fan), and I was just wondering what others think of his feelings for her, considering it’s a pretty important part of his character and motives. I’ve seen a lot of people find it creepy, which is understandable, but I’m still unsure what to think. Lmk!
