Heart touching and Heart breaking. Give it a shot dude. It has some insane character development. Overall it's beautifully spun, giving stress on side characters and using them to enrich the story. Moral and teachings too along with spices of philosophy and psychology. Human nature and best part is Subaru's struggle to not lose his human nature.
The relation between live and try to live are shown. Some insane waifu designs...(rem-rin :) and beautifull romances.

BUT THE BEST PART IS HOW IT SHOWS THE TRUE CONCEPT OF LOVE.

(Ofcouse I am straight)
