Jack and the Cuckoo-Clock Heart

Jack is born with his heart frozen solid on the coldest day in history.

A wise midwife saves him by replacing it with a cuckoo clock.

Now Jack must abide by three rules to keep his mechanical heart safe: never touch the clock's hands, master his anger, and never fall in love.

He tries his best, but when he meets a girl named Acacia he falls in love, threatening the delicate balance of his artificial heart.
