She's a cold woman in early 20's, never wanted to be understand by outsiders. She lost her family, thanks to accident. She's a cold woman in 20's, working in an ice factory, colder in the winter or spring, and wishing to die.
He's a bright man in early 30's, brighter than sunflower, loves being close without suspicious. He's a bright man in early 30's, wishing his time will be ticking longer than his weak heartbeat.
