what other areas do we love with our eyes apart from nature?

I would say, arts - paintings, drawings, sculptures, murals and even architectural designs (buildings) etc.

how can someone be repelled by nature?

When I’m in nature, like when I go camping every now and then, the first thing that repels me is the swarm of mosquitoes treating me like an unlimited buffet. Yes, nature is beautiful, but that beauty can fade fast once it reveals its true self – like getting to know someone and discovering certain mannerisms that irritates you.
Forests may look enchanting, but once you’re there, suddenly you’d have to deal with insects, poisonous plants, and hoping you don’t cross paths with something venomous. Deserts? Surreal, yes, but merciless to the unprepared – your awe quickly turns to dehydration. And the ocean? Absolutely mesmerizing, until it capsizes your boat, indifferent to your struggle to stay alive. Sometimes, nature can be very harsh and unforgiving...but it's precisely these contradictions that make them intoxicatingly beautiful.
