Happy World!

Takeshi has learned to expect disaster wherever he goes. An inherited curse seems to poison even ordinary moments, until the angel Elle offers him a chance to escape it. Rather than secure his own happiness, he chooses to help a girl in need.

Elle stays beside him as his protector, bringing an unfamiliar presence into his troubled daily life. Yet companionship cannot simply erase old wounds, and she must learn how complicated human pain and affection can be. Their bond grows through the difficult choices that come with caring for someone whose life has rarely been kind.
