Chanho is a brilliant scientist he's made contraptions to make you look younger, skinner, and older. Using the machine to make you younger does have side effects, it makes you less mature. He's only used it once, turning him in to the beautiful 17 year old he once was. One day when he was at his lab he made a contraption that might be his greatest creation yet. A human like robot that goes by the name of Sparks (Yeah.. his immaturity is already showing). He had been working on thing one for many months, but he can't seem to get the damn thing moving... It's missing something but he can't figure it out. A battery... No, he may be immature but he's not stupid. One day the answer walked up to him. A heart, but he would never and I mean never kill anyone... right? His 15 year old dog died and he did what any other scientist in need of a heart would do. After checking to make sure his poor blinker was actually dead, he started his experiment. After he remade the heart so it was strong enough to last a very long time. He put the heart in sparks, but it still wouldn't work. He gave up covering sparks with a tarp, pushing it to the corner of his lab. A half a century went by and he never spared a glance at it until his neighbors daughter snuck into his lab.
